Synapse Pipeline Error: Bad Request

Z.K.Z 206 Reputation points


We occasionally encounter the following error during the execution of several of our pipelines in Azure Synapse Analytics:

{ "errorCode": "BadRequest", "message": "The request failed with status code '"BadRequest"'.", "failureType": "UserError", "target": "prod1", "details": "" }

This issue seems to occur sporadically, and when we rerun the affected pipeline, it usually completes successfully without any further errors.

    Hi @Z.K.Z

    Welcome to Microsoft Q&A platform and thanks for posting your question here.

    The Bad Request error you're facing in Azure Synapse Analytics can be caused by a few different issues. It's possible that there is an intermittent issue with the pipeline configuration or execution that is causing the error to occur sporadically. When you rerun the affected pipeline, it's possible that the issue has resolved itself or that the pipeline has been able to work around the issue.

    To troubleshoot the issue further, you can try enabling diagnostic logging for your pipelines to capture more detailed information when the error occurs. This can help you identify patterns or specific conditions that lead to the failure. Additionally, you can check the Azure Synapse Analytics service health status to see if there are any known issues or outages that could be causing the error.

    It's also possible that the issue is related to resource constraints or configuration errors. Double-check for any incorrect references or typos in your pipeline configuration, ensure there are no unintended spaces in the name of one of the pipeline execution tasks, consider reducing the number of vCores requested or increasing your vCore quota if there are not enough resources available in the workspace at the time of execution, and verify that all configurations are correct and published in the linked services or datasets.

    Hope this helps. Do let us know if you any further queries.
