This issue has only happened since last week. I have two sharepoint lists (lets call them list A and list B) that the app updates. When the users click on button to send email for notification the app updates list B but does not update list A and get the attached error messages. No changes were done to the app and this issue suddenly appeared. I have already tried solutions on the boards like changing the formula First for Lookup, re-connecting to the SP list.
I went into Edit mode and only used the code to patch to list and was working ok, so then I told users to start using it again but it keeps coming up with the error attached. The ids change every error message.
The frustrating thing is that there are other buttons that update list A and there is no issue with them, it is only this particular code which updates customer names, approval status, approver and value that is not working and hence app can no longer be used.
So, this error is most likely coming from SharePoint, so either they made a change to SP Online that is casuing it, or there was a connector chnage that is causing it.
@JKarnesBloomin, are you still experiencing this ETAG mismatch error?
Would you be able to provide a session ID and a fiddler trace? I can jump on a call and help you with this if you send me a PM.
I am also seeing this same issue with a submitform .. Intermittant issue... mostly does not work anymore but will sometime work in dev studio
Data Source is a Task list in SharePoint...
Have tried replacing the connector with no luck
Just started heppening in the last week or so..
Session ID: 88a3da59-3cb7-487c-84ed-b0070a160b4a
error message states
"Conflicts exist with Changes on the server, Please Reload. Server Response ETAG Mismatch
I found a pattern easy to reproduce
I republished the app and an item will save fine on the first edit and save but you will get this the second time you edit and try to save.
This is very consistant an easy to reproduce.
Open item and edit and save - no problem. Open another list item and save - no problem. Go back to first item and try and save - you get the error. Go to the second item that you edited and try and edit and you get he same error
So here is the pattern
Open an item and save - works fine. Open the saved item and edit and try and save - you get the error.
So Ill throw my app in the ring as well. Every app we use that connects to sharepoint is suffering from the dreaded ETAG issue. Just want to ditto what @skylitedave has described. I found the same pattern... I thought it was intermittant but when I refresh the browser and reload our apps the first save for each record will be sucessful. Any second edit throws an error, always the same error, and we have to refresh the browser and reload the app to clear it.
Microsoft must have changed something in the sourcecode with powerapps or sharepoint over the last week.
It is not a random error. It is easy to reproduce.
Happens every time
data source SharePoint lists
Workaround for now
This has been validated by several users
This has been open for a week with no updates from Microsoft.
Can someone from Microsoft respond and let us know what is going on to resolve this serious bug? This is being reported by many users.
To recap.. the issue is this....
If you connect to a SharePoint list and try to edit a list item more than 1 time in a session you will get this error when you use patch or submitform unless you issue a refresh ( and that is a suboptimal workaround since it involves a roundtrip to the server before you save)
