[webyneter]

What:
Collectfast==0.6.0 and boto3==1.5.8 don't play well when deploying to Heroku, resulting in

I'm also using:

django-storages==1.5.0  # pyup: ==1.5.0

Solution:
Downgrade

Collectfast==0.5.2 # pyup: ==0.5.2

That looks like it's related to django-storages and not to boto3. Does upgrading django-storages help?

[webyneter]

@antonagestam sorry for the late response, I will try upgrading django-storages to 1.6; thank you for the tip :)

[antonagestam]

@webyneter No worries. Thanks for reporting the bug!
