Hi, Eric.
We’ve created inner task BKNDLSS-16117 and investigate this problem.
We’ll reply to you as soon as there is a new information.

Ok thanks

What’s the current status on the migration issue?

Hi Eric

developer is working on it now, we will notify you about any result as soon as possible

Regards, Vlad

OK, Please do.

Hi Vlad,

What’s the progress so far?
Currently my app can’t login any users due to the migration issue therefore I need to get it running soon.

Thanks in advance

This problem has been fixed.
Production servers will be updated in next one-two days. As we’ve mentioned above we will notify you here ASAP.

Ok thanks. Let me see if the app works as expected now.


Currently my app is unable to add any data to the database. Getters and setters method are not working

We are currently updating production servers with the necessary code to fix the migration problem you’ve described. It will be available in 30-60 minutes. You’ll need to process the migration again, after that I’d recommend to generate classes for your data tables (in Code Generation section in your backendless application) and then try again.

If the issue with getters and setters will still persist - create a separate support topic with description of how to reproduce the problem.

Best Regards

Production servers have been updated with a fix.
Please verify

Best Regards

Thanks, it’s working fine now
