rbw generate stopped working at some point. rbw list and get work
correctly, but not saving the password. example:
[REDACTED]
rbw generate: failed to parse JSON: missing field `access_token` at line 1 column 25
So the password gets generated, but something breaks when it's trying
to upload it.
The remote server is a "vaultwarden" server running the latest Docker
container (pulled today, 11a8641850b2), but it was also failing with a
3-weeks old container (9f8daa3a7526).
I have not tested against a stock upstream. Upgrading to 1.15.0-1
makes everything worse: instead of crashing with a JSON error, it
hangs after generating the password, and now even `rbw get` fails.
