Node.js
spawn
andspawnAsync
APIs seem rather unreliable in terms of collectingstdout
andstderr
that occurs close to spawned process terminating (see, e.g., nodejs/node#19218). We need thestderr
of processes terminating with status code>1
to understand which validation error occurred. This PR increases the resilience of accessing thestderr
output by wrapping ansh
shell around the invocation of the otelcol binary.
