Deploy error while developing a timer

Hi team,

the following error has been occured:
Backendless encountered an error while handling the request. An internal trouble ticket with ID bl-server:02B96A0D-BADA-F118-FF3C-49C694BC3F00 has been created and we will be investigating the issue.

I was deploying a service when this window popped up:

Server changes could not have happened to my knowledge as I am just working in a single browser window.

What is the best advice you could give how to proceed?

Regards, Joerg

The more interesting effect is that a JSON column is not updated in this timer sequence.
In your latest blog about the outage you mentioned something about problems with JSON fields.

Could you please check the error.

Thank you in advance.

Hello @Jorg_Beyer

This warning appears when you try to deploy a model whose code differs from the code of the deployed model.
If you want to see the differences, then you can use Changelog.
