Refresh error

[Maheshguptaz]

Hi,

I'm facing the below error with my scheduled refresh on of the report which is connected via the gateway and all the data sources in this report are CSV files saved on a shared drive. Any help on getting this resolved will be really appreciated

Data source error:

{"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":"The column '' of the table wasn't found."}},{"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: AcademyTraining.

Regards,

Mahesh

Hi, @Maheshguptaz 

Have you modified the column names in the source data or deleted a column? These operations may cause the refresh to fail. Please check it.

You can try to open the local pbix file, then open the power query, then click the refresh button to refresh the data, then save the report and re-publish it to the pbi service.

Did I answer your question? Please mark my reply as solution. Thank you very much.
If not, please feel free to ask me.
