versions: 2.4.0, 2.5.0 and @hackmd/hackmd-cli/2.5.0-beta.20260527230745.bf73672 linux-x64 node-v22.22.1

How do I fix this?

Start by running the `hackmd-cli login` entry point with the token that succeeds against `GET https://api.hackmd.io/v1/me` via curl, and compare the CLI request with that working request. Use the reported versions as reproduction targets; done means login succeeds with the same valid token instead of retrying and reporting invalid credentials.
