@Edgar Ramírez (Arch.dev) Do I need to update my Tap config values in Meltano Hub to for new config values passed via env var to my tap to be recognized e.g.,

MY_TAP_MY_NEW_VALUE=foo

I remember at some point in time I realized that there is a check for valid config values against Meltano hub but can't recall if that is still the case (or my understanding from the start could be wrong).

In general, yes. You could temporarily add it in

settings

in your local

meltano.yml

for testing purposes.
