[bug]: pulsarctl 3.1 branch can't work with client credentials error

[ericsyh]

Background

I tested and found that pulsarctl 3.1 branch release can't work now which will get error like

pulsarctl topics list public/default
[✖]  client error: could not get client credentials: open : no such file or directory

But I the pulsarctl 3.0 branch works well and won't get this client credentials error.

How to reproduce

I upgraded the pulsarctl on local Mac laptop the version is

Release Version: 3.1.0.2
Git Commit Hash: cb9b6f620364a7cea19325ae2c82523d08265520
Git Branch: HEAD
UTC Build Time: 2023-08-30 09:48:42
Go Version: go version go1.18.10 linux/amd64

Then run any kind of regular commands will get the client crediential error

pulsarctl tenants list
[✖]  client error: could not get client credentials: open : no such file or directory

@tuteng @zymap @mattisonchao Could you help check this issue?

encountered same error

change to Release Version: v2.10.5.11-5ce22c is working.

Same here, when using latest version and client_credentials it fails with error:

client error: authentication failed using client credentials: could not exchange client credentials: AADSTS90014: The required field 'scope' is missing from the credential. Ensure that you have all the necessary parameters for the login request.

However, when downgrading to v2.10.5.11-5ce22c it works without issues.

Not that using service account admin credentials works fine with both version, but we need to use client_credentials to scope operations to particular namespaces and topics.

@balticore According to the error, do you have the scope in the client credential file?
