I’m getting this error under very specific circumstances:
I have deployed a VM via docker-machine. I want to run a docker container with the stock starport project, it’s called launchpayloadcli/launchpayloadd inside it.
If I run docker-machine ssh machinename docker run --volume=/home/docker/nodeconfig:/payload/config -p 1317:1317 apeunit/launchpayload /payload/runlightclient.sh 192.168.99.100 drop-28b10d4eff415a7b0b2c, or put the command in a .sh file in the VM, this error DOES NOT appear when I access a particular API endpoint (GET IP:1317/txs/TXHASH)
If I write a Golang program to run this exact same command, including the docker-machine ssh part, it will give this error when I access that particular API endpoint:

It has something to do with CLI’s config files --home ~/.launchpayloadcli/CHAIN_ID, perhaps the .lite_verifier, because if I don’t get the error, I can scp the files into the VM and I won’t get this error anymore.
It doesn’t seem to be a file permissions error because the files can be created. But what could cause that specific line /home/shinichi/source/go/pkg/mod/github.com/tendermint/tendermint@v0.33.7/lite/dynamic_verifier.go:76 +0x6c to panic?
