gh issue list ... --milestone [value] -> illegal base64 data at input byte 2 #4040
Description
Describe the bug
On a private repo, I'm trying to list issues with the gh command. Never had any issues until this particular milestone where I get
$ gh issue list -R [repo name] --milestone 63
illegal base64 data at input byte 2
# same issue with the string
$ gh issue list -R [repo name --milestone "Iteration 223"
illegal base64 data at input byte 2
The same command works successfully with other milestone values
gh version 1.13.1 (2021-07-20)
