ETAG Mismatch - App WAS working for months

Received reports this morning of ETAG errors showing. This application has been working for months and the patch code below has not changed. High level of the workflow.... user clicks button in a gallery to add an update, patch takes that update and writes it to the record selected when clicking the button.


Patch('CPP Milestones',LookUp('CPP Milestones',ProjectPlanGallery.Selected.ID=ID),{Milestone_Update:DataCardValue1.Text,Last_Milestone_Update:Today(),Milestone_Update_Count:ThisItem.Milestone_Update_Count+1,Milestone_Hours:ThisItem.Milestone_Hours+AddMilestoneUpdateHours});

Powerapps version: 3.18124.26

Hi @maverick17


IS this when Patching to SHarePoint Online lists ?






Hi @maverick17


I am on PowerApps version 3.19012.19 when this started to happen.


It was fine before then.





This has been working for months and all of the sudden this morning users are reporting the issue.


My app is on 3.18124.26

BUMP, any help with this?

ETAG Errors still happening in version 3.19012.19

Frequent Visitor

I've found the same thing. Patch functions that have been working for over a year suddenly have ETAG errors.

My observation though was that this was only affecting my apps when the 'Patch' was updating an existing record whereas it worked fine on new items being patched into the (in my case) SharePoint list (i.e. Patch(ListName,Default(ListName),{....}) works fine)
I've worked around this instead by using UpdateIf(...) for these parts of my app to update the existing records in my SharePoint lists, which for now at least is working.

Hope that helps...

Anybody from Microsoft Chasing a solution for this ?
