Patch error: The specified column is read-only and can't be modified

[biterbit]

I have two apps that were recently updated using Power Apps Studio release 3.23113 and, since those releases, half of my users (about 70 people) have experienced errors when patching records: Network error when using Patch function: The specified column is read-only and can't be modified. The columns referenced in the error are two Choice columns in a SharePoint list. The columns have not changed in two years.

I am unable to reproduce the error in either the Studio or production environments.

The only reliable way to stop these errors is for the users to log out of their 365 session and log in again. However, after about two weeks of managing these problems, I am now finding users getting the errors again for the second time. 

I found this thread about a similar problem, but the proposed solution was to revert to an earlier Studio release. However, that option is not longer available as new releases have occurred. I have tried re-releasing the apps using newer Studio versions (up to 3.23121), but the errors continue.

In the earlier thread, the problem was described by @v-jefferni as 'a known issue'. If so, is there any news on when it will be solved as the support cost of managing many users with this intermittent issue is very high?

Were you able to release with the latest version and did it resolve the issue?

@lcordov2 It's early days, but so far today I have had no errors reported, compared to 11 yesterday and 24 the day before. The version I used was 3.23122.13. I will be applying this version to my other apps that are exhibiting this issue in the hope that this is the fix.

My issues were with version 3.23114.19/24/25. Republished on 3.23121.20 (latest version available to me) 4 hours ago and have since had no issues. Fingers crossed!

Update 18/12: Come in this morning to no issues over the weekend - looks like it's sorted

I can also confirm no errors since making the change 72 hours ago.

It still does not work for me. I am working on a SharePoint integrated form. Only available version is 3.23122.17

[biterbit]

That version is very close to the one which worked for me. Have you been able to identify the columns which are reporting as read-only?

Hi Everyone,

I am receiving this error on all of my Canvas applications with PATCH function. It was working pretty fine with the App release (3.24034.17) (currently published). But it gives the error: Network error when using Patch function: The specified column is read-only and can't be modified. This error started appearing after I have saved the app in the latest release (3.24042.28). (Not allowing me to make any updates). 

The PATCH function updates a choice column based on a dropdown value and another date field which auto-updates to today() date.

PS: I am unable to update the Authoring version as when I click on Edit, I see only the newer releases and no older releases. When I try updating to the new one and hit Reload + Apply version, it loads, displays Power Apps logo in the middle and nothing happens even after a while. Please help if there are any leads or anybody else is facing similar issues.

Have you checked that you don’t have any calculated columns added to your form?

Had the exact same problem.  Seems to be resolved in 3.24043.33

Thank you for mentioning this! This was exactly my problem regarding this issue. I commented out the Calculated field from my Patch statement and the error went away! Thanks very much!
