Error on refresh

[RYoud]

Hi,

New to PowerBI and had very basic training, I have an error on scheduled refresh, no idea what to check?  Any advice would be greatly appreciated.

{"error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","pbi.error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","parameters":{},"details":[{"code":"DM_ErrorDetailNameCode_UnderlyingErrorCode","detail":{"type":1,"value":"-2147467259"}},{"code":"DM_ErrorDetailNameCode_UnderlyingErrorMessage","detail":{"type":1,"value":"<ccon>The column '' of the table wasn't found.</ccon>"}},{"code":"DM_ErrorDetailNameCode_UnderlyingHResult","detail":{"type":1,"value":"-2147467259"}},{"code":"Microsoft.Data.Mashup.ValueError.Detail","detail":{"type":1,"value":""}},{"code":"Microsoft.Data.Mashup.ValueError.Reason","detail":{"type":1,"value":"Expression.Error"}}],"exceptionCulprit":1}}} Table: Student Data.

Hi @RYoud ,

Providing only a partial error code is not enough to do further investigation, can you describe the specific scenario in which the problem occurs?
Also please provide a detailed error message, which usually appears as a summary sentence on the page where the problem occurred.
Thanks in advance!

Best regards.

Hi,

This error is occurring when the scheduled refresh is attempting to run in the PowerBI service.
