Power Apps Canvas App Version 3.22022.23 BUG on SaveData() – There was a problem saving your data. Name could be too long.

[DKassian]

Following update to Power Apps version 3.22022.23 a bug has been identified that is impacting 100% of our production and development applications that use the SaveData() function, where as soon as the collection being saved has a certain number of records in it, there is an error “There was a problem saving your data. Name could be too long.” displayed to the user.

See screenshot from production application displaying this error:

To better test the issue, we created a simple canvas app that has the following functionality:

1. Number entry box to define number of records to collect,
2. Button to collect a single column collection, with n number of records from step 1
3. Button to run “SaveData” function on the collection created in Step 2

Using this test app, we were able to determine the number of records stored in a collection that will then start returning an error is between 1700 and 1720. This aligns to the issues we are seeing in our production apps. This is not a large number of records for an enterprise application, and to date we have never had these issues.

Our testing indicates so far that the data is indeed being saved, despite the error message. However, it is causing mayhem with users when they see error messages in the field. This is completely unacceptable to have this behavior change in an “enterprise grade” platform. We have had to roll back apps to prior versions to prevent this error message from displaying. At this point we are effectively unable to create or update any of our applications.

TEST APP, no error:

TEST APP: Errors

We have performed some additional test scenarios:

1. Collection is single column, and contains a single integer in each cell:

Record count where error is displayed: 1,700 to 1,750

1. Collection is multi column, and contains 150 words of random text in each cell (much larger collection):

Record count where error is displayed: 1,700 to 1,750

This testing leads us to believe it’s a count of records issue, not an issue with the size of the collection or the amount of data stored in the collection.

I hope someone is able to provide a solution to this bug, I have a ticket in with Microsoft, and will update this post with their response.

Hey everyone. I was having the same issue, but I updated my app to version 3.22034.17 and the issue is gone for me. I am using over 1800 records in my collections and SaveData/LoadData functions.

Nightmare
I have now tried versions...

3.22041.23

3.22034.17

3.22022.31

3.22022.34

Either I get this bug, or my app literally does not open in some versions. I'm at my wits end. 

Any update from Microsoft??
