Gemini fails to authorize: hermes rewrites auth.json access_token key

[grave bolt]

~/.hermes/auth.json setup records my AI Studio key incorrectly which causes auth failure.
It saves mykey\x01\x0bmykey as "access_token" which fails
If I edit auth.json , hermes just sets it back.
I've put the key in .env but that does nothing.
