Hi,

I'm using python 2.7 and the config file method with the packages used in the requirements file. I'm coming across the following error:

File "mendeley-catalog.py", line 23, in
session = mendeley.start_client_credentials_flow().authenticate()
File "/home/rafael/anaconda2/envs/mendeley/lib/python2.7/site-packages/mendeley/auth.py", line 31, in authenticate
token = oauth.fetch_token(self.token_url, auth=self.auth, scope=['all'])
File "/home/rafael/anaconda2/envs/mendeley/lib/python2.7/site-packages/requests_oauthlib/oauth2_session.py", line 199, in fetch_token

File "/home/rafael/anaconda2/envs/mendeley/lib/python2.7/site-packages/oauthlib/oauth2/rfc6749/parameters.py", line 386, in validate_token_parameters
raise MissingTokenError(description="Missing access token parameter.")
oauthlib.oauth2.rfc6749.errors.MissingTokenError: (missing_token) Missing access token parameter.

Could you please advise on how to solve this? Thank you.

I get the oauthlib.oauth2.rfc6749.errors.TokenExpiredError after some time has past, and even when I restart the server it keeps showing this message

I cloned the repo.
I created app:

id=1055
key=provided secret here
redirect_uri=http://localhost:5000/oauth

I updated the config.yaml with above key and secret.

I ran the script and got the below.

ubuntu@ip-10-63-175-117:~/mendeley-api-python-catalog-example$ python mendeley-catalog.py

Please help.

Thanks

I have fetched git repo and made "pip install -r requirements.txt" and checked that everything has installed.

silpol@hostname:/tmp/mendeley-api-python-catalog-example$ pip install -r requirements.txt -U

Then I re-used OAuth credentials from previous test. Then launched script as described in readme. It looks like OAuth passed just fine. Then I get prompt

Enter a DOI:

for which I provide DOI for existing document 10.1145/1815961.1816021

and then I get exception

silpol@hostname:/tmp/mendeley-api-python-catalog-example$ python mendeley-catalog.py 
Enter a DOI: 10.1145/1815961.1816021
Traceback (most recent call last):
  File "mendeley-catalog.py", line 12, in <module>
    doc = session.catalog.by_identifier(doi=doi, view='stats')
  File "/usr/local/lib/python2.7/dist-packages/mendeley/resources/catalog.py", line 47, in by_identifier
    raise MendeleyException('Catalog document not found')
mendeley.exception.MendeleyException: Catalog document not found

Is this expected behaviour or malfunction?
