a few lines above it

Yes both things can be true. Oauth authorization can complete successfully and you may not have access to

/api/1.0/Account

from here you have to debug why the

/api/1.0/Account

call is failing. I try to change the error message in my taps so we can see the body of the 401 response as that normally gives you clues. The other way to debug this is to manually pull the data from that endpoint on your own (Postman, curl, etc) get the data working then figure out what's going on in the tap. Ideally the tap would give you more info as to what's going on

thanks @visch !

I normally add a proxy in the middle to debug HTTP issues. For Meltano SDK based taps, using a HTTP proxy requires this patch though: https://gitlab.com/cwegener/sdk/-/commit/d593bdddbea951095bdc5f3edfc38623b0b10909

@christoph fiddler?

@christoph fiddler?

Yeah. That's one example. Charles Proxy, Proxyman and many others would likely do the job as well. I personally only use

mitmproxy

for HTTP debugging.
