Hey folks,

I'm trying to get this example code working, as it is pretty close to something I want to build. I keep getting this error in the oauth package. I installed the packages in requirements.txt and am running python within a fresh virtualenv. Anyone have any ideas? Here is the stack trace:

    Is this still an issue of you?

    Yes, I gave up trying to get the API to work because I was having this error with the example Python code and a similar error with the JavaScript example code.

    For the thing I'm trying to build this is not a problem, since I realized all of the information I want is contained in the BibTeX file I can export from Mendeley Desktop anyway.

    same here, when running Authorization code flow, I always get this error.

    albus1993 As I said above I actually gave up on trying to get the API to work. I was trying to basically work with my own library, so I found it easier to export it to BibTeX and use a parsing library to import that into a database. If that fits your use case I would recommend trying it - there are BibTeX parsing libraries for most programming languages.

    I concur with this error. Any luck figuring out how to fix it? Perhaps an example using flask-oauthlib, with documentation shown here, would be most useful?

    Apologies for not getting back to you on this. Can someone please share their code with me? e.g the exact steps that is causing this?

    Missing the access token parameter means exactly that - maybe something is stripping it out? I'll take a look - Python is not my strongest language so I may need some help.

    I was running your catalogue example as it is: https://github.com/Mendeley/mendeley-api-python-catalog-example in python 2.7 and using the config file method.

    Thanks.

    Are you using a virtualenv or just doing exactly what the instructions say?

    No environments, like the instructions.

    I've committed an update to the Mendeley dependency so can you try again. Perhaps create a virtualenv to ensure you have a dedicated environment. I'm struggling to replicate it but we will update some dependencies and see if any one of them will fix the issue as I research it in the background.

    Also can you run a 'pip freeze' and show me your output.

    I've created an environment using conda and python2 for this and above is my 'pip freeze' result. Clear chache and cookies because of ipython notebook? I'm running it from a unix terminal in this case.

    It's because I am referring to the mendeley-api-python-catalog-example (https://github.com/Mendeley/mendeley-api-python-catalog-example) and not the mendeley-api-python-example. I saw that the mendeley-api-python-example had the same error as I had with the mendeley-api-python-catalog-example and I was checking if anyone had the solution. Apologies if it's not the appropriate channel but the error is the same.
    So my packages are in line with the required ones in the catalogue example.

    OK I'm confused now. Can we shut this issue and move it to the correct one?

    No need to apologise.

    Are we discussing the Missing Token error or the state error?

    For what it is worth, the config example does not make clear that the {} are not required around the id and secret.

    If loaded with the {} the config is loaded with the following format

    {'clientId': {my_client_id: None}, 'clientSecret': {'my_secret_string': None}}

    Importantly this leads to the Mendeley authentication containing a password that is now a dictionary {'my_secret_string': None} and the same with the password {my_client_id: None}

    I have to run but eventually this leads to the "Missing access token parameter" error reported above. Perhaps this is the problem that people are encountering? ....

    @MendeleyStack - Sure, I will open an issue on mendeley-api-python-catalog-example. It's the missing token error.

    Jim Hokanson (@JimHokanson) - I've seen that too and corrected so that the dictionary has only one entry. Still have the same missing token error.

    Same problem.

    From the Werkzeug debugger (EDIT: from fetch_token in requests_oauthlib/oauth2_session.py):
    r.text is a 401 with u'{"message":"Credentials are required to access this resource."}'
    print(auth.username) => My Mendeley app id
    print(auth.password) => My Mendeley client secret

    Jim Hokanson (@JimHokanson) I removed the {} from config.yml.

    I'm running from Python 2.7.11 in a new Anaconda environment, with requirements built with pip install -r requirements.txt.
    pip freeze:
    arrow==0.5.0
    certifi==14.5.14

    I was facing the same issue for an hour or so today. I had been able to get the example to work last week or so. Finally I realized I made a stupid mistake, I did not update the secret after generating a new one. Complete waste of an hour.

    Hey,

    Have you got something like this in your config.yml file?

    clientId: xxxx
    clientSecret: fsfjasfkljf
