Error: oauthlib.oauth2.rfc6749.errors.MissingTokenError about mendeley-api-python-example HOT 25 OPEN

Is this still an issue of you?

from mendeley-api-python-example.

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.

from mendeley-api-python-example.

I have been able to recreate this and I am working on a fix.

from mendeley-api-python-example.

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

from mendeley-api-python-example.

@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.

from mendeley-api-python-example.

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?

from mendeley-api-python-example.

what is the status of this?

from mendeley-api-python-example.

I had this problem too, any news if it has been solved? Many thanks.

from mendeley-api-python-example.

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.

from mendeley-api-python-example.

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?

from mendeley-api-python-example.

No environments, like the instructions.

from mendeley-api-python-example.

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.

from mendeley-api-python-example.

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

from mendeley-api-python-example.

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.

Have you run pip install -r requirements.txt ?

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.

from mendeley-api-python-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?

from mendeley-api-python-example.

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? ....

from mendeley-api-python-example.

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

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

from mendeley-api-python-example.

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

@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.

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.

from mendeley-api-python-example.

Hi, Can someone tell me how you fix the Missing access token parameter?

from mendeley-api-python-example.

Hey,

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

clientId: xxxx
clientSecret: fsfjasfkljf
