So trying to setup the Ecobee integration for the first time, and after putting in my auth code, I get a javascript error and seem unable to add this app. It opens up to present the login web auth just fine, but it's after putting in the MFA code it sits for a while (about 10 seconds) then just shows the error:
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data.
Anyone else run into this or have some ideas on what I can try?
