Hi @ViliusZigmantas. I am having a similar issue with my install process. This reply of yours helped me to confirm that my /installed route is working. The reply I got is: “Installation verification error: 401 No baseUrl provided in registration info.”
I could use some help putting together the data for the POST /installed call from Postman to get closer to the source of my issue. I have not found any description of that call
If you or any other could have a look at it and reply to me in my thread: Cannot install ACE React app from Heroku
All help very much appreciated
