gmail.users.threads.get hangs forever

[wdanilo]

Environment details

• OS: MacOS Ventura 13.2
• Node.js version: v21.4.0
• npm version: 10.2.4
• googleapis version: 105.0.0

Steps to reproduce

Reproduction is not simple. Basically:

1. I have a custom email client which fetches threads from GMail.
2. I am able to fetch 1867 threads without issues, but there are 3 threads with IDs that I noted down, that hang up gmail.users.threads.get forever (it is never resolved nor rejected).
3. If I hardcode these 3 IDs in my code to skip them, everything works fine.

I'd be happy to provide additional data if needed. Also, I tested these IDs on the Google API website API tester and it provides correct result, so it seems like this is an issue with this library.

Actually, I just tested my program without

google.options({
      http2: true,
    })

An it appears that it works. It seems that gmail.users.threads.get hangs on these threads only if http2 is in use.
