Azure Data Factory - Data Flow: Internal Server Error:Failed to submit job on instance pool. Integration Runtime 'wirInt'

Question

Hello, I am trying to create Data flow inside ADFs when I am preparing it inside debug mode, everything is working. Once I published it and try to trigger it after about 30s I receive this error: "Error 135, Internal Server Error: Failed to submit job on instance pool. Integration Runtime 'wirInt'". I have tried different integration runtimes. Is there someone who has managed it?

Answer 1

Find out that this issue is based on unsupported "Latin" letters like "ščřžý" in the Resource Group name. Build data flow in another resource group without them it's working as it should.

Hi @Štěpán Rešl ,If you are using self-hosted integration run time, please go through below documentation to troubleshoot:

Answer 3

Hi @Štěpán Rešl , unfortunately, Azure doesn't have robust list of error code which explicitly gives out cause and

probable workaround. All I could see is below which is not comprehensive enough

Meanwhile below question on the similar lines was asked before, error code is different but

worth giving a shout. Thanks
