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.
