If the caller does not have permission to update the [Engine][google.cloud.discoveryengine.v1beta.Engine], regardless of whether or not it exists, a PERMISSION_DENIED error is returned. If the [Engine][google.cloud.discoveryengine.v1beta.Engine] to update does not exist, a NOT_FOUND error is returned.
updateMask	FieldMask Indicates which fields in the provided [Engine][google.cloud.discoveryengine.v1beta.Engine] to update. If an unsupported or unknown field is provided, an INVALID_ARGUMENT error is returned.
callSettings	CallSettings If not null, applies overrides to this RPC call.

Returns
Type	Description
TaskEngine	A Task containing the RPC response.

Example

// Create client
EngineServiceClient engineServiceClient = await EngineServiceClient.CreateAsync();
// Initialize request argument(s)
Engine engine = new Engine();
FieldMask updateMask = new FieldMask();
// Make the request
Engine response = await engineServiceClient.UpdateEngineAsync(engine, updateMask);
