Hi,
Welcome to the community!
You can certainly generate a user token from a user with global analysis rights and use it for all your pipelines. There’s no need at all to generate a token per project if you don’t want to.
Regarding the error you got, can you provide the full analysis log?
The analysis / scanner log is what’s output from the analysis command. Hopefully, the log you provide - redacted as necessary - will include that command as well.
This guide will help you find them.
