Unknown render failure. Cannot read properties of undefined (reading ‘ProgId’)

Question

Hi. It seems Microsoft Lists was updated today in my company, the list website looks a bit different and refreshed, the views are now shown in tabs, however this is causing an error when we edit an item from lists that have a custom form in Power Apps. Once we save the item, the data's is saved and we are redirected to a page saying: Unknown render failure. Cannot read properties of undefined (reading ‘ProgId’). I couldn’t find anything about this error online. I haven’t changed anything in the form recently. This error wasn’t happening yesterday and it’s now happening with 2 different lists. Can someone assist?

Answer 1

I found the issue. I have a grouping in All Items view, I removed it and the error is no longer appearing. I believe this is something that needs to be investigated, it seems to have nothing to do with Power Apps.

Answer 2

I have the same issues described that started with the new Sharepoint online. We are using a custom view with grouping that is necessary. If anyone finds a work around please share.

Answer 3

Hello. I had grouping set up in my All Otems view, I removed the grouping in edit view and this solved the issue.

Answer 4

We are also having this issue. When we remove groupings or the form (independently) it solves the rendering error. However, there are 200+ items within this list, so the groupings are crucial. We also value the form because only certain fields are required based on other fields. How would I solve this if I cannot remove groupings or the form?

Answer 5

Hello friend, I have the same error. Could you give more details on how you solved it please?
