Has anyone else run into issues where a newly-installed tap seems to run successfully (e.g. no errors thrown) but also without any logs indicating successful data transfer? I originally thought this was a problem specific to a particular tap, but I’ve now seen it happen with

tap-jira

,

tap-mailchimp

, and

tap-typeform

, which makes me think I’m missing something a little more fundamental. if I do

meltano select tap-mailchimp --list

for all of these, I get “Cannot list the selected attributes: Could not find catalog. Verify that the tap supports discovery mode and advertises the

discover

capability as well as either

catalog

or `properties`“. While the docs for these taps aren’t extensive, I think based on a scan of the code (here’s an example) that discovery mode is supported. Anyone have ideas on where I should dig next?

@nick_hamlin What

capabilities

have you listed for these plugins? Are you including

discover

and

catalog

?

ah! do you need to list those explicitly? I didn’t do that for other (working) taps

Yep, Meltano won't know that the tap supports discovery or a catalog unless you tell it 🙂 Not knowing that, it would run the tap in sync mode without a

--catalog

at all, and neither of these branches would be entered: https://github.com/singer-io/tap-mailchimp/blob/master/tap_mailchimp/__init__.py#L37-L43

yeah, that’s definitely what happened - I’m gonna let mailchimp finish syncing and see if that also solves typeform (I suspect it will). Once I get those going, I’ll circle back on jira. Thanks!
