Hello everyone, first of all, sorry if this is wrong category, but I’m stuck as hell here.
I tried to configure the google mail integration and after going through the calendar one I thought this’ gonna be easy.
Hell no, after going through the complete process (OAuth and what not) I got to the final step - link my account and bam…it hits me up with a pop-up that only says ERROR. But nothing else 
anyone got that happen? How did you solve it?
TIA!
I’m sorry I can’t describe the error more. I also get error with the config_flow.py
Today I realized what was wrong I forgot to enable the gmail api in the console. Anyway, this is the solution… problem is, that the error pop-up had absolutely nothing and the integration data gets stuck in home assistant without any chance to get it away.
so I did go into storage and in app_authorization I had to remove the lines regarding mail and then it was all beans! 
I’m having the same exact issue / error. Only thing is, the gmail api **is enabled!
Can you provide more details on your comment " so I did go into storage and in app_authorization I had to remove the lines regarding mail…"?
I’m really sorry, but I don’t remember
i had this, caught me out for about 30 mins, you have to go back to
and click the link in ’ SCENARIO 1’ step 1 and enable it again.
