Error Connecting to SharePoint List (500): Internal Server Error

[Anonymous]

With no changes made to the source SharePoint list my report refresh started failing this morning with the error below.   I've had this happen on a different list and never found a fix for it.


Error:
DataSource.Error: Web.Contents failed to get contents from 'https://sharepointed.sharepoint.com/sites/fun-stuff/_api/Web/Lists(guid'9ab1335c-b8fe-1b99-be01-77d5...' (500): Internal Server Error

we had the same behavior on one of our lists, that had 20k items long time woking an suddenly did not work anymore.
We found, that there was an aggregation (count) set in the default view of the list. So even, if you use the "all" setting, which should ignore all view settings, the aggregation setting of the default view seems to result in an error.

So for us, removing the aggregation from the default view of the list, solved this issue.

Hi, can you help me with this "removing the aggregation from the default view of the list" - how could I do it?

Thanks!

[DaFloDo]

hi @Ola_G,
in the SharePoint list, in the upper right of the list, select the default view and then click on edit current view.

if there is an aggregation for any of the columns, set it to "none". This was fixing the problem for us.

Don't forget to save these changes

Unfortunately didnt help 😞 but @DaFloDo thanks anyway!

You're kidding!! Am I to understand the Power Bi literally just stops working when a SharePoint list crossed the view threshhold and there is no solultion?

I am experiencing the same issue. Did anybody ever find the solution? Thanks

Nope, opened a ticket with Micorosft Premier support and they said it's a SharePoint issue.  SharePoint support said nothing can be done.  a lot of wasted time.
.
I thought the point of using the Power BI 2.0 connection to SharePoint was to leverage paging and avoid issues like this.

Hi @Anonymous ,

If you have multiple queries and when refreshing, Power BI evaluate and refresh all queries at the same time.

This may be the cause of this error.

Please try turning off the parallel data loading in the options for data load.

That will then not load the data in parallel but rather one at a time.

Best Regards,
Liang

Cleared cache(s)
Updated the setting you mentioned
Createad a new report

Source:
SharePoint Online List
2.0 option
Selected the list

Same error noted above.

The 2.0 Implementation must be used due to the size of the SharePoint list.
