No JSON object could be decoded

[Fkawala]

Hi,

I have trouble using queues (python-librato/librato/queue.py). I create the queue as demonstrated in the docs (see below). The queue auto-submit fails with a ValueError exception that is raised when the response from the server is parsed.

Best,
François.

Minimum example:

LIBRATO_USER = '****'
LIBRATO_TOKEN = '****'
api = librato.connect(LIBRATO_USER, LIBRATO_TOKEN)
q = api.new_queue(auto_submit_count=1)
q.add('sdfsdf',1)

Error stack:

The problem is related to the authentication. The content of the response that cause the ValueError is:

Credentials are required to access this resource.

@Fkawala Thanks for the report and update. The regular maintainers of this lib are out for the next few days (this is a Holiday week in the US), but they should be able to follow up in improving this case next week.

It sounds like it was an auth issue, were you able to get everything sorted in the meantime?

@nextmat Thanks for the update, that auth issue is solved.
