During update of an Azure Stream Analytics Job, I get HTTP 422 Unprocessable Entity

During an update of streaming jobs (via REST Api, we use the generic one that allows to update any kind of resource: https://learn.microsoft.com/en-us/rest/api/resources/resources/updatebyid), I get 422 without any additional information. Could anyone help with identifying the problem ?

Solution

  • Well, although there is very little useful information in your question, I eventually reproduce your issue on my side.

    enter image description here

    The reason has been described clearly by the error message :

    PATCH of Inputs, Transformation, Functions, Outputs or Devices is not allowed using the Streaming Job level API. Please use the API for the corresponding resources.

    This means you could not include the Inputs, Transformation, Functions, Outputs, Devices in your request body, because they are different resources form the streamingjobs.

    Solution:

    To fix the issue, just use the API for the corresponding resources as mentioed in the error message.

    1.Update Input : PATCH https://managment.azure.com/subscriptions/{subscription-id}/resourceGroups/{resource-group-name}/providers/Microsoft.StreamAnalytics/streamingjobs/{job-name}/inputs/{input-name}?api-version={api-version}

    2.Update Function : PATCH https://<endpoint>/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.StreamAnalytics/streamingjobs/{jobName}/function/{functionName}?api-version={api-version}

    3.Update Output : PATCH https://managment.azure.com/subscriptions/{subscription-id}/resourceGroups/{resource-group-name}/providers/Microsoft.StreamAnalytics/streamingjobs/{job-name}/outputs/output?api-version={api-version}

    4.Update Transformation : PATCH https://management.azure.com/subscriptions/{subscription-id}/resourceGroups/{resource-group-name}/providers/Microsoft.StreamAnalytics/streamingjobs/{job-name}/transformations/{transformation-name}?api-version={api-version}

    For more details, you could refer to Stream Analytics REST API.

    Sample:

    I test to Update Input.

    PATCH https://managment.azure.com/subscriptions/xxxxxx/resourceGroups/joywebapp/providers/Microsoft.StreamAnalytics/streamingjobs/joyteststream/inputs/joyinput?api-version=2018-11-01

    Request body:

    {    
   "properties":{    
      "type":"Stream",  
      "serialization":{    
         "type":"JSON",  
         "properties":{    
            "encoding":"UTF8"  
         }  
      }  
   }  
}

    Result:
