Forms connection with bdm after upgrading Bonita

Hello!

I have upgraded Bonita from 2021.1 to 2022.1 on a cloned test server before doing it on the production server. Just in case.

The migration was without errors, but I have detected that in all forms, do not load the information from the BDM from custom querys, for example in Combobox.

I was checking the server log and there are no errors. If I run process from Bonita Studio 2022.1 works perfect.

Export the BDM again from Bonita Studio 2022.1 and import to the server with the new version but it didn't solve the problem.

Can you suggest me some kind of workaround to find out what might be going on?

Do you think it is better to update from version 2021.1 to 2021.2 and then from 2021.2 to 2022.1?

EDIT:

New information in case it helps:
I cloned the version of one of the 2021.1 version processes in Bonita Studio 2022.1 and installed it in Bonita Runtime 2022.1 and the connection with BDM worked perfectly.

The problem is that this is not a good solution because the processes that started in Bonita 2021.1 could not be completed
