Run doctor-sdk with bucket password as argument

I am trying to run this command: sdk-doctor diagnose couchbase://127.0.0.1/default
This is the repo: https://github.com/couchbaselabs/sdk-doctor
But I need to pass as argument the bucket password, someone knows how to do this?
Thanks!

hi Im not able to run sdk-doctor . Im getting sdk-doctor not a command error

Can you paste what you’re typing into the shell? You may need to set it as executable (chmod a+x sdk-doctor) and you may need to execute it as ./sdk-doctor. What OS too?
