@Gilgamesh
Hello, Gilgamesh. First of all, I apologize for not being able to provide a positive answer. I have confirmed the occurrence of the issue you reported in a test environment with the same error log, but I have not yet found a clear solution. I am trying a few different approaches, but I expect that resolving this compatibility issue will require more time.
