I'm using the Saas module from "Pragmatic". Suddenly, I started to receive an error.

In order to correct the error, I restored a backup from May 2020. When I made the backup, there was no error.

However, even after being restored, the error continues.

I'll copy below:

Erro:

Can you tell me, please, why you are giving this error and how to fix it?

If I returned a backup that did not exist, why is it happening now?

Thanks in advance for your help.
