Unable to decode response: 756 (twitter over capacity) #22

Closed vtsatskin closed 12 years ago

vtsatskin commented 12 years ago

While running some rspec tests that use grackle, Twitter was over capacity.

The code run:

client = Grackle::Client.new
client.statuses.user_timeline.json? :screen_name => 'vtsatskin', :count => 200, :page => 1

This was the output:

    Grackle::TwitterError:

While I agree the output could be improved, it's reasonable for Grackle to raise an exception if Twitter returns a response that's not in the format that was requested (in this case html when json was requested). You'll need to rescue the TwitterError and decide what you want to do as a result of this condition.
