Thanks for the report @euskadi31, how do I reproduce this error ?

@cneira
This log message comes from hashicorp/go-plugin and is just saying that you haven't opted into the stdio service per hashicorp/go-plugin#142 and doesn't necessarily mean that anything is wrong.
What you can do is explicitly drop the message ala grafana/grafana#23601 or let people ignore it (although some people may be tripped by seeing what sounds like an error like @euskadi31 and I were)
