I created a PowerApp by customizing a SharePoint form. Nothing has changed on the SharePoint list recently. When I open the PowerApp now all of my choice fields show a red X error of "The data source supplied to the function is invalid."
If I refresh the SharePoint data source, then the error goes away but all of my choice fields break. They essentially stop being choice fileds and don't work at all.
I am not using any other data sources.
There is a lot of logic built into the form, so removing and re-adding the fields is not a good solution.
I'm having this same error, Have a form that's been used for weeks.. I really had not touched it but noticed today that some of my fields don't save when user enters them. I opned the form and found all these have this error ' data source supplied to function is invalid'. I've not changed anything. I tried to do the save and go back in as per Microsoft suggestion but it still has the error so I'm afraid to publish now. What did you do to get past this latest bug!
Hi Just adding my voice here, i got the same error message today using patch on collection generated via collect on SQL table. At runtime the function still works, so not a problem for me at present, but still there...
Thank you. This workaround helped me to fix the issue. I was getting this error when I moved a solution that included apps and flows to a new environment.
Any update on when the fix would be available?
