Cannot create agent when `.env` contains empty vars

[korya]

Creating agent with lk agent create fails when .env contains an empty env var (a var with empty value).

The error is twirp error internal: failed to convert secrets

A sample .env file to reproduce:

FOO=1
BAR=
BAZ=3

Here is the full log:

❯ lk agent create --verbose --secrets-file .env.lk

Changing the .env file to

FOO=1
BAR=2
BAZ=3

solves the problem.

This is an error on the service side, not on the CLI. Will log the issue in appropriate place. cc @yoonsio

Thanks!

I would argue that the issue should stay open until it is fixed. Unless it is a nofix.

By the end of the day, the lk tool fails. For me as the end user, it does not matter if it is a server side error or a client side. My experience is the Livekit agents tool fails as a whole.

Also, is the service side open source? If not, is there any ETA on this issue?

@korya no, the service is closed-source. I'm happy to leave it open as a placeholder until we resolve on our end.
