Re: Server Response ETAG mismatch clientRequestId serviceRequestId

This is the status quo functional progression of Power Apps @JKarnesBloomin . Stub features are released and refined by frequent updates. Microsoft is "silently advancing" the code base to the destination in a nebulous "evolutionary" model based on requests and acceptance. At times, there are "issues" we surface as a community, and they are quickly dealt with when we make noise. We are both the user base, and a beta test population all rolled into one. It is the next logical advancement of what started as the "open source movement" or the "code consortium" models, but now they get instant, live feedback to any tweaks they make. A corporate "authority based" structured approach to community involved development, that has the advantage of Azure AD infused security protections, and data connectors to third party data stores. We are the PowerApps community! ( Think "windows for workgroups" instead of a corporate OS, they are moderating "app features" for the community. ) From Microsoft, with love ;-) @SmartMeter

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.

Re: Server Response ETAG mismatch clientRequestId serviceRequestId

@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.

Re: Server Response ETAG mismatch clientRequestId serviceRequestId

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

Re: Server Response ETAG mismatch clientRequestId serviceRequestId

 

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.

Re: Server Response ETAG mismatch clientRequestId serviceRequestId

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.

Re: Server Response ETAG mismatch clientRequestId serviceRequestId

What we have found is that the ETAG error is quite random. I have two folks function testing for "timeout" or tenant connection from stale sessions or ? From what I can tell, this whole architecture is supposed to be stateless, and adding MFA with an authenticator on the device makes the waters even more murky for this type of thing. Over the course of the last two days I have focused on another project, but I will be back to this in a few days. Incidentally (In case anyone else has) I just added functionality to use the first attachment as an image from the gallery, and the app user can attach one image to the SP list object. I kind of hard coded the gallery to use attachment 1 and the gallery just displays one image from ATT1 in turn. All ETAG and invalid data source errors STARTED with the same release that the image attachment capability went live in. My best to all those suffering through this, @SmartMeter

Re: Server Response ETAG mismatch clientRequestId serviceRequestId

It is not a random error.  It is easy to reproduce.  

  • Log in
  • Edit and item and Save - no problem with Patch or SubmitForm
  • Edit same item again in same session - ETAG error with Patch or SubmitForm

 

Happens every time

data source SharePoint lists

 

Workaround for now

 

  • Log out and log back in to edit or
  • Issue Refresh before Patch or Submitform

 

This has been validated by several users

Re: Server Response ETAG mismatch clientRequestId serviceRequestId

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)

 

Thx
