session POST request return NULL token

I tried to create a new Session (using Traccar's API with swagger.json) but it always returns NULL as token's value even I created token using Account dialog. (I only created token, doesn't change anything else in Account dialog)

But after I changed another option in Account dialog (example: Timezone or token expiration date), the API can returns token's value.

Is it a bug of Traccar Server?

If you see token in the Account dialog, you should get the same value through the API.

Anton,

I tried with 2 servers and both of them have same problem. I can see token in the Account dialog but the API returns null.

To be noted that I installed a clean server then generate token only (don't change anything else in the Account dialog). But after I change other option (example: expiration date or timezone), the API now returns token's value.

Please provide steps to reproduce on a clean account.

Seems it happen with v3.10. Cannot reproduce after upgrading to v3.11.
