It looks to me like you might have found a bug, I created an issue to track it
https://gitlab.com/meltano/meltano/-/issues/3301, feel free to add more detail to that issue. It looks like youre installing with the UI, alternatively you can use the CLI to do the same thing until the bug has been resolved. (cc
@florian.hines @alexmarple since I think you guys were working on the UI/API recently)
