Unstable work of PowerApps with SharePoint online lists. SharePointListTableDataController

[Oleks]

The previously created application today began to have issues with reading from and writing data to Sharepoint online lists:

After several link updates, some errors disappear and others appear

Hi @Oleks,

Thanks for the feedback.

Are there any changes have been made under the SharePoint Online lists?

Per my testing, PowerApps has no issues when working with the SharePoint Online list (Custom List).

Also it would be helpful if you could share something about the ShareQPoint list fields type, and the related configurations.

Regards,

Michael

Hi Michael

There are not any changes have been made under SharePoint lists. The lists have Number, Single line of text and Lookup columns. All these lists are related with each other by lookup fields with enforcing relationship behavior.

Can anyone from PowerApps Staff tell me what the issue is?

I found that other users encountered similar issue:

Hi v-micsh-msft

FYI our app was built 1 month ago with 4 SharePoint lists which fields did not change for the last 15 days.

During last 15 days, we performed about 200 user tests and everything went well until last saturday when these messages appeared.

Data has never been corrupted and has always been accessible, app works well except that these messages appear now continuously.

The only thing we tested last saturdday is changing back and forth the List Option from "Read all items" to "Read items that were created by the user" but after complete rebuilding of the list, messages are still displaying

I am starting to see the same error across all of our apps that are connected to SharePoint lists. The affected apps have been working for the past 4 weeks. What can be changed on my end to rectify?

I'm getting the same errors - starting today when it was working fine yesterday. Made a new thread here: https://powerusers.microsoft.com/t5/PowerApps-Forum/Server-Error-accessing-SharePoint-list/m-p/54262...

Must be something on MS backend.

Seems the error is occuring again. Are you able to repeat the fix?
