ScriptEvaluationFailed
Kode error
steps.script.ScriptEvaluationFailed
Isi respons error
{"fault":{"faultstring":"Evaluation of script pythonscript_name (py) failed with reason: error_type: error_description"","detail":{"errorcode":"steps.script.ScriptEvaluationFailed"}}}
Kemungkinan penyebab
Kebijakan Python Script dapat
menampilkan beberapa jenis error ScriptEvaluationFailed. Bagian di bawah menjelaskan beberapa error ini.
NameError
Jika ada variabel dalam kode PythonScript yang direferensikan atau dioperasikan tanpa ditentukan, Anda akan mendapatkan error Nama.
Isi respons error
{"fault":{"faultstring":"Evaluation of script pythonscript_name (py) failed with reason: "NameError:variable_nameisnotdefined"","detail":{"errorcode":"steps.script.ScriptEvaluationFailed"}}}
Contoh isi respons error
{"fault":{"faultstring":"Evaluation of script myscript.py (py) failed with reason: "NameError:'num3'isnotdefined"","detail":{"errorcode":"steps.script.ScriptEvaluationFailed"}}}
Diagnosis
Identifikasi kebijakan PythonScript dan nama variabel yang tidak ditentukan dari elemen faultstring respons error. Misalnya, dalam faultstring berikut, nama PythonScript adalah myscript.py dan nama variabel yang tidak ditentukan adalah num3:
"faultstring":"Evaluation of script myscript.py (py) failed with reason: "NameError:'num3'isnotdefined""
Periksa file sumber PythonScript yang diidentifikasi pada langkah #1 di atas dan pastikan apakah variabel yang tidak ditentukan yang diidentifikasi pada langkah #1 di atas sedang dirujuk. Misalnya, kode PythonScript berikut mereferensikan variabel yang tidak ditentukan num3, yang cocok dengan faultstring:
num1=1.5num2=6.3sum=float(num1)+float(num3)print('The sum of {0} and {1} is {2}'.format(num1,num3sum))
Periksa apakah variabel tertentu ditentukan dalam kode PythonScript. Jika variabel tidak ditentukan, hal itu adalah penyebab error.
Dalam contoh skrip yang ditampilkan di atas, variabel num3 tidak ditentukan. Oleh karena itu, Anda akan mendapatkan error di bawah ini:
"faultstring":"Evaluation of script myscript.py (py) failed with reason: "NameError:'num3'isnotdefined""
Resolusi
Pastikan semua variabel yang dirujuk dalam kode PythonScript ditentukan dengan benar.
Untuk memperbaiki masalah pada contoh PythonScript yang ditampilkan di atas, tentukan variabel num3 sebelum menggunakannya. Contoh:
num1=1.5num2=6.3num3=8.7sum=float(num1)+float(num3)print('The sum of {0} and {1} is {2}'.format(num1,num3,sum))
ZeroDivisionError
Error ini muncul saat argumen kedua dari operasi pembagian atau modulo adalah nol.
Isi respons error
{"fault":{"faultstring":"Evaluation of script pythonscript_name (py) failed with reason: "ZeroDivisionError:reason_for_error"","detail":{"errorcode":"steps.script.ScriptEvaluationFailed"}}}
Contoh isi respons error
{"fault":{"faultstring":"Evaluation of script myscript.py (py) failed with reason: "ZeroDivisionError:integerdivisionormodulobyzero"","detail":{"errorcode":"steps.script.ScriptEvaluationFailed"}}}
Diagnosis
Identifikasi nama kebijakan PythonScript dan alasan kegagalan dari elemen faultstring respons error. Misalnya, dalam faultstring berikut, nama PythonScript adalah myscript.py dan alasan kegagalannya adalah integer division or modulo by zero:
"faultstring":"Evaluation of script myscript.py (py) failed with reason: "ZeroDivisionError:integerdivisionormodulobyzero""
Periksa file sumber PythonScript yang diidentifikasi pada langkah #1 di atas dan verifikasi apakah ada operasi pembagian atau modulus dengan nol. Misalnya, kode PythonScript berikut melakukan pembagian dengan nol, yang cocok dengan yang ada di faultstring:
a=0b=5c=b/aprintc
Dalam contoh skrip yang ditampilkan di atas, karena argumen kedua operasi pembagian adalah nol, Anda akan mendapatkan error berikut:
"faultstring":"Evaluation of script myscript.py (py) failed with reason: "ZeroDivisionError:integerdivisionormodulobyzero""
Resolusi
Pastikan argumen kedua operasi pembagian atau modulo bukan nol di PythonScript.
Untuk memperbaiki masalah pada contoh PythonScript yang ditampilkan di atas, gunakan nilai non-nol sebagai argumen kedua dari operasi pembagian atau modulus. Contoh:
a=3b=5c=b/aprintc

Please let us know by clicking [Send Feedback]().\n\nScriptEvaluationFailed\n----------------------\n\n### Error code\n\n steps.script.ScriptEvaluationFailed\n\n### Error response body\n\n```python\n{\n \"fault\": {\n \"faultstring\": \"Evaluation of script \u003cvar translate=\"no\"\u003epythonscript_name\u003c/var\u003e (py) failed with reason: \u003cvar translate=\"no\"\u003eerror_type\u003c/var\u003e: \u003cvar translate=\"no\"\u003eerror_description\u003c/var\u003e\"\",\n \"detail\": {\n \"errorcode\": \"steps.script.ScriptEvaluationFailed\"\n }\n }\n}\n```\n\n### Possible causes\n\nThe [Python Script](/apigee/docs/api-platform/reference/policies/python-script-policy) policy can\nthrow several different types of `ScriptEvaluationFailed` errors. The sections below describe some of these errors.\n\nNameError\n---------\n\nIf there is a variable in the PythonScript code which is referenced or operated on without being defined, then you get the Name error.\n\n### Error response body\n\n```python\n{\n \"fault\": {\n \"faultstring\": \"Evaluation of script \u003cvar translate=\"no\"\u003epythonscript_name\u003c/var\u003e (py) failed with reason: \"NameError: variable_name is not defined\"\",\n \"detail\": {\n \"errorcode\": \"steps.script.ScriptEvaluationFailed\"\n }\n }\n}\n```\n\n### Example error response body\n\n```python\n{\n \"fault\": {\n \"faultstring\": \"Evaluation of script myscript.py (py) failed with reason: \"NameError: 'num3' is not defined\"\",\n \"detail\": {\n \"errorcode\": \"steps.script.ScriptEvaluationFailed\"\n }\n }\n}\n```\n\n### Diagnosis\n\n1. Identify the PythonScript policy and the undefined variable name from the faultstring element of the error response. For example, in the following faultstring, the PythonScript name is `myscript.py` and the undefined variable name is **num3**:\n\n ```python\n \"faultstring\": \"Evaluation of script myscript.py (py) failed with reason: \"NameError: 'num3' is not defined\"\"\n ```\n2. Examine the PythonScript source file identified in step #1 above and verify if the undefined variable identified in step #1 above is being referenced. For example, the following PythonScript code references the undefined variable **num3**, which matches the faultstring:\n\n ```python\n num1 = 1.5\n num2 = 6.3\n sum = float(num1) + float(num3)\n print('The sum of {0} and {1} is {2}'.format(num1, num3 sum))\n ```\n3. Check if the specific variable is defined within the PythonScript code. If the variable is not defined, then that's the cause for the error.\n\n In the example script shown above, the variable **num3** is undefined. Therefore, you will get the below error:\n\n \u003cbr /\u003e\n\n ```python\n \"faultstring\": \"Evaluation of script myscript.py (py) failed with reason: \"NameError: 'num3' is not defined\"\"\n ```\n\n \u003cbr /\u003e\n\n### Resolution\n\nEnsure that all the variables referenced in the PythonScript code are properly defined.\n\nTo fix the issue with the example PythonScript shown above, define the variable **num3** before using it. For example: \n\n```python\nnum1 = 1.5\nnum2 = 6.3\nnum3 = 8.7\nsum = float(num1) + float(num3)\nprint('The sum of {0} and {1} is {2}'.format(num1, num3, sum))\n```\n\nZeroDivisionError\n-----------------\n\nThis error is raised when the second argument of a division or modulo operation is zero.\n\n### Error response body\n\n```python\n{\n \"fault\": {\n \"faultstring\": \"Evaluation of script \u003cvar translate=\"no\"\u003epythonscript_name\u003c/var\u003e (py) failed with reason: \"ZeroDivisionError: reason_for_error\"\",\n \"detail\": {\n \"errorcode\": \"steps.script.ScriptEvaluationFailed\"\n }\n }\n}\n```\n\n### Example error response body\n\n```python\n{\n \"fault\": {\n \"faultstring\": \"Evaluation of script myscript.py (py) failed with reason: \"ZeroDivisionError: integer division or modulo by zero\"\",\n \"detail\": {\n \"errorcode\": \"steps.script.ScriptEvaluationFailed\"\n }\n }\n}\n```\n\n### Diagnosis\n\n1. Identify the PythonScript policy name and the reason for failure from the faultstring element of the error response. For example, in the following faultstring, the PythonScript name is `myscript.py` and the reason for failure is `integer division or modulo by zero`:\n\n ```python\n \"faultstring\": \"Evaluation of script myscript.py (py) failed with reason: \"ZeroDivisionError: integer division or modulo by zero\"\"\n ```\n2. Examine the PythonScript source file identified in step #1 above and verify if there's a division or a modulus operation by zero. For example, the following PythonScript code performs division by zero, which matches with what's in the faultstring:\n\n ```python\n a = 0\n b = 5\n c = b/a\n print c\n ```\n\n In the example script shown above, because the second argument of the division operation is zero, you get the following error: \n\n ```python\n \"faultstring\": \"Evaluation of script myscript.py (py) failed with reason: \"ZeroDivisionError: integer division or modulo by zero\"\"\n ```\n\n### Resolution\n\nEnsure that the second argument of a division or modulo operation is non zero in the PythonScript.\n\nTo fix the issue with the example PythonScript shown above, use a non zero value as the second argument of a division or modulo operation. For example: \n\n```python\na = 3\nb = 5\nc = b/a\nprint c\n```\n\nMore Information\n----------------\n\nThere are many other possible causes for the error `steps.script.ScriptEvaluationFailed` apart from the ones described above. Please refer to the official [Python documentation](https://docs.python.org/3/library/exceptions.html) for more information."]]
