Dataflows & Sharepoint task lists - Get data error

[Anonymous]

Hi PBI Community,

I have been trying to connect sharepoint lists into a dataflow, to have all of my sharepoint lists in one place to select for reporting. I've come across a strange inconsistency between power bi dataflows and power bi desktop.

I am able to get data from the sharepoint lists option in power bi desktop when the list type is list and tasks list. Yet when I try to load from the exact same source in power bi dataflows, an error is returned for the lists that are the tasks list list type. The general list type list connect fine. Again, PBI desktop connects lists and tasks lists without error.

The error is: DataSource.Error: SharePoint: Request failed: The remote server returned an error: (500) Internal Server Error. (An error occurred while processing this request.)

Could anyone advise why there might be this inconsistency between power bi desktop and dataflows? Is it a bug?

HI @Anonymous,

What type of SharePoint does your test? Sharepoint online or SharePoint on-premise? I'd like to suggest you use the corresponding connector to get data.

You can take a look at the following link to know more about different SharePoint connectors:

Your data source can't be refreshed because the credentials are invalid 

In addition, you can also try to use other connectors to get data from SharePoint list: (e.g. OData connector: SiteURL/_vti_bin/listdata.svc)
