How to solve the getting your data error message in PowerApps

Question

Dear all,

 

I hope you can help me with the following. I have created a list in SP Online and a PowerAutomate flow on this list. Now I would like to add a Powerapps form to this list to make the user experience more friendly. Therefore I have opened the default form with Powerapps. This opens Powerapps for this particular list.

After that I have added a new screen in PowerApps:

When I try to open the new screen in the list, I get a getting your data error message:

I have set the default screen to a custom Powerapps form in the form settings of the list:

Could you please tell me how I can solve this problem?

Thanks. Yannick
