Can't get PIN for Ecobee binding

I recently learned that there is some complicated situation with service configurations under OH2/ESH/Karaf. I suggest trying some of the suggestions in this post:

I don’t know if it’s a documentation or code issue, but there is a lot that can surprise the user in the area of configuration (in comparison to openHAB 1.x).

Please let us know if you are able to track down the bad config data and what you did to sort it. Thanks!
