Yup, same issue. My implementation hasn’t been touched in days, worked fine until now.
Been trying to debug this for hours now, thought I was going nuts until finding this.
Feather Finance’s OAuth code has not changed in 3 weeks (and everything was working smoothly until yesterday)
existing access_tokens are still working, but we cannot generate new ones
To troubleshoot we created a New Connected App, and tried to do the OAuth flow in Postman, but Postman is throwing the same error message.
We also generated a new Client Secret to see if the old one had been invalidated, but the oauth/token returns the same error message with the new Client Secret.
What’s most puzzling to us is that the TradingView integration does NOT seem to be impacted by this. I linked my Alpaca account to my TradingView account for the first time this morning…
@Dan_Whitnable_Alpaca, just wanted to make sure you are aware of this thread – yesterday’s maintenance seems to have broken the OAuth flow for many apps.
