Can't get into dnscrypt-proxy container in balena-pihole project

Running balena-pihole and loving it! But noticed one thing which makes it look broken for me:
when trying to get into the dnscrypt-proxy container, receiving:

$ balena ssh dnscrypt-proxy
OCI runtime exec failed: exec failed: container_linux.go:345: starting container process caused "exec: \"/bin/sh\": stat /bin/sh: no such file or directory": unknown
Connection to closed.

Similar results in BalenaCloud shell:

I supposed to be able to get there, right?
Please let me know whether it works for anybody or if I am wrong in my expectations…
Thank you

Ok, just got an answer on github issue if anyone is interested.
