Getting rake / gem error on Update 5.4.1 -> 6.0.0

Hey, I managed to update to 6.3.1 by creating a new stack with the v9.0.2 script and ENV-vars, loading the psql-backup manually, and then incrementally updating with the scripts from the repo going over every mayor and minor version (don’t miss 11.1, 11.2 and 11.3)

But still have some proglems: WebUI can't query Data after Update

Good luck!
