I'm building an Electron App with an agent that uses BoxLite. I accidentally passed process.env to Node SDK by SimpleBox. I encountered this error:Timeout waiting for guest ready (30s)

I ran ./target/debug/boxlite run --rm $(printenv | sed 's/=.*//;s/^/-e /' | tr '\n' ' ') docker.io/library/alpine:latest echo ok, got the same error.

How to reproduce

./target/debug/boxlite run --rm $(printenv | sed 's/=.*//;s/^/-e /' | tr '\n' ' ') docker.io/library/alpine:latest echo ok

env var numbers

(base) goranka@fengbolins-MacBook-Pro boxlite % printenv | wc -l
59

Execution log

(base) goranka@fengbolins-MacBook-Pro boxlite % ./target/debug/boxlite run --rm $(printenv | sed 's/=.*//;s/^/-e /' | tr '\n' ' ') docker.io/library/alpine:latest echo ok
