Powerapps Error after Refershing Data Source (SharePoint List)

[Omardith20]

Hello,

I am have an existing PowerApps canvass application. I added new columns in SharePoint List.

After refreshing data source in my PowerApps canvass, I got a hundreds of runtime error in every combo boxes inside my form control.

Please see image below.

Note: I haven't experienced this kind of error from previous months.

Thank you.

Hi! Did the errors appear after using this Refresh button? Or did you remove and re-add the data source?

Hi - I'm having the same problem - has been happening for about a week. I added one or 2 new fields in the Sharepoint list and have refreshed the data sources numerous times. I even created a brand new app from scratch and re-added the same data source only to find the little red error circles coming up on all my dropdown lists controls. This happening on my work PC when I am logged into the work network however when I go home and get on my iMac and open Powerapps (signed in as the same work email) everything behaves perfectly!!

I am very confused why this would happen - any ideas?

thanks

Yes, i added more than 2 new fields and then click that button. Then I was prompted with hundreds of error "Data supply is not valid"  and all my number fields columns has an error of  "we cannot convert value empty"

Yes that's correct. I also added new columns then clicked Refresh Data Source in my canvas.

Do still encountering this error?

I cannot create the app from the scratch because this is a huge application 😞

I resolved the problem by creating a brand new Sharepoint list as my data source. I made sure I named the fields exactly the same as in the original list, then when I had finished simply added the new list into my app and changed datasource from old to new. It worked perfectly.

However today, 5 days later I opened my app in Edit mode and after a couple of minutes all the runtime errors came up for all the dropdown lists in my app. I thought the app was corrupted or something but I waited for about 5 mins and all the errors magically disappeared again!  I think I have to wonder if this is a bug in Powerapps....anyway, for now, my app seems to work perfectly and I have confidence in it again going forward.

 Hi , I am facing the exact same issue. Did you ever find the root cause or any solution to this?

 @SC05 Hi, I didn't find a logical solution - some things seem to crop up but then resolve themselves without any interaction. I can only suggest creating a new Gallery or Form and put a couple of controls on and see if it's OK and go from there - good luck!
