conf_page_maker throws unhandled exception

[danwos]

I'm calling conf_page_maker like

conf_page_maker publisher.yml --user [email protected] -pid 12345123

My publisher.yml config file:

version: 2
url: https://xy.atlassian.net/wiki
base_dir: _build/json/
pages:
- title: test me

As you can see, I'm trying to run this on Atlassian Cloud.
However, during execution I get the following exception:

Traceback (most recent call last):
...
  File "/home/daniel/workspace/envs/sphinx/lib/python3.5/site-packages/conf_publisher/confluence_api.py", line 64, in _request
    ret = r.json()
  File "/home/daniel/workspace/envs/sphinx/lib/python3.5/site-packages/requests/models.py", line 866, in json
    return complexjson.loads(self.text, **kwargs)
  File "/usr/lib/python3.5/json/__init__.py", line 319, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python3.5/json/decoder.py", line 339, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python3.5/json/decoder.py", line 357, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

I'm not sure if this error is thrown, because my config is a mess and the script can't open a file and therefore sends 0 bytes. Or if confluence is sending back 0 bytes.

Any ideas?
