Error fetching repo list from Bitbucket

Hi, I am trying to upgrade from drone:0.7 to 0.8.4.

I am unable to fetch repositories from Bitbucket. The Bitbucket setup should be correct as it was previously working with 0.7 version. I also tried to generate new Bitbucket OAuth access, but I am getting the same error:

client error 500: Error fetching repository list. sql: Scan error on column index 12: sql/driver: couldn’t convert () into type bool

(see for better error description)
