File contains corrupted data issue

[faustusxanthis]

My dashboard is already published in PowerBI online. If I refresh the dashboard using desktop, the refresh completes without any error. I checked Power Query and no tables are showing any errors. However, when I refresh the said dashboard online or do a scheduled refresh, it always gives me a "DataFormat.Error: File contains corrupted data" error!

I checked the source file of the referenced table and the file loads just fine. There are no passwords or anything. The Excel file loads without any problem. 

I also checked the Power Query for the referenced table in Desktop and it's not showing any error. 

I'm wondering what could be the issue here?

Could you specify the path used when publishing to the service? Is this referencing an Excel file on a mapped drive (eg. Z:\myexcel.xlsx) or using a \\server.domain.com\myexcel.xlsx) ? Do you require a gateway? The service has to be able to reach the file

It's on Sharepoint

Could this be related to specific fields (like a date, date time, ...) contained in the file? It might use a different locale when processing on your local machine vs the service.

you could troubleshoot by just keeping 1 column from the file (eg a string or an int) and refresh the dashboard in the service. That could point to the culprit.

I will check on this. Right now, I'm still having issues
