@thomas-mcdonald not sure if you want to accept this, but just making the issue known.

You can see the issue in the object above. The reputation attribute is the #<Serel::Relation:0x007f85c5147650> and not the integer value.

@thomas-mcdonald is it possible to get this merged, I'm also going to try to implement a refresh! method to refresh an expired token, I've ran into issues with my token expiring.

Well I figured out you can actually get non-expiring tokens by adding 'no_expiry' into scope

provider :stackexchange, ENV['STACKEXCHANGE_CLIENT_ID'], ENV['STACKEXCHANGE_CLIENT_SECRET'], public_key: ENV['STACKEXCHANGE_PUB_KEY'], site: 'stackoverflow', scope: 'no_expiry'
