Input and output error codes

Stay organized with collections Save and categorize content based on your preferences.

The I/O metric charts use canonical error codes. If these error codes persist in your sources and sinks, refer to the following list for potential causes and actions you can take.

  • RESOURCE_EXHAUSTED. The project might have run out of resource quota for the service the source or sink is using.

    If the error occurs occasionally or when the Requests per sec chart indicates a high volume of requests being made, then this might indicate that you have reached an API rate limiting quota and need to increase the quota.

  • DEADLINE_EXCEEDED. Source or sink might have timed out reading or writing a large batch of data. Check the latency chart and worker logs. If the error persists, contact support.

  • INVALID_ARGUMENT. Parameters specified to the source or sink might be malformed (such as a Pub/Sub topic). Check configuration of the source or sink, and check the worker logs.

  • FAILED_PRECONDITION. Check configuration of the source or sink, and check the worker logs. This could also indicate a bug.

  • OUT_OF_RANGE. Check that the resource being used by the source or sink exists (such as a Pub/Sub topic or subscription).

  • UNAUTHENTICATED. Check that the Dataflow service account has Identity and Access Management permissions to the specific service and relevant APIs are enabled for the project.

  • PERMISSION_DENIED. Check that the Dataflow service account has Identity and Access Management permissions to the specific service and relevant APIs are enabled for the project.

  • NOT_FOUND. Check that the entities being used by the source or sink exist (such as a Pub/Sub topic or subscription).

  • ABORTED. Service might not be properly handling the source or sinks attempts to read or write data. If the error persists, contact support.

  • ALREADY_EXISTS. I/O might be trying to create an entity which already exists (such as a Pub/Sub topic or subscription). If the error persists, contact support.

  • CANCELLED. This can occur when a Dataflow worker is shut down or source or sink logic intentionally decides to cancel attempts to read or write data.

  • DATALOSS. Indicates unrecoverable data loss or corruption occurred. You might want to create a new dataset for your sources and rerun the Dataflow job.

    You might also see if there are any backup and restoring instructions available for the underlying Google Cloud service.

  • UNKNOWN. Service might be down. Check for updates on Cloud Status Dashboard for more information.

  • INTERNAL. Service might be down. Check for updates on Cloud Status Dashboard for more information.

  • UNAVAILABLE. Service might be down. Check for updates on Cloud Status Dashboard for more information.

  • UNIMPLEMENTED. The source or sink attempted to use the service in an invalid way. Your pipeline might be misconfigured. If the error persists, contact support.
