Ive tried a different attribute as well, as i thought maybe it could only handle strings, such as brand or name, and not floats like B7, but none work. With or without quotes around the attribute, etc.
Also, size works just fine, so its just something to do with attribute specifically.
It was merged, I checked this periodically but did not see working.
Also, there was not a release created since that PR.
May be, only Readme was updated?
Or both Readme and a code were updated - but Release was not created?
