I am receiving the following error message after I register my app with reuters through the pytho...

Hi @michael-r.meyer

This may not be the exact same issue that you are facing - but an internal user had a very similar error message/ usage scenario and it was down to an incompatible version of http3 library when using Python 3.6

For that user, the following resolved the issue:

pip uninstall http3 
pip install http3==0.6

An alternative option would be to try Python 3.7 which the RDP library dev team advises they have validated and certified with this version.

Hi @Antonios.Antoniadis

I have been advised by the RDP Dev team that they were able to reproduce what appears to be the same issue (i.e. same error message etc) with Python 3.6 - but could not be reproduced with 3.7 and also that version 1.1.5 of the Eikon library has been tested + qualified with Python 3.7 (but not 3.6)

Therefore, if you are able to test with v3.7 please do so.

@Antonios.Antoniadis

Eikon Data APIs Python library v1.1.6.post2 is now available from PyPI. We believe this version of the library addresses various connection problems some users experienced with Eikon Data APIs Python library v1.1.5. Could you update the version of Eikon Data APIs Python library on your machine to v1.1.6.post2 and reply back on this thread if it helped?

NoneType object has no attribute status_code¶

I had this exact same issue and tracked it back to a timeout in the nest_asyncio.py dependency.

In [3]:

import eikon as ek

ek.__version__

Out[3]:

'1.1.5'

This is just a helper function to demonstrate the source code we're looking at.

In [8]:

import inspect

def show_source_code(module, start_line, end_line):
    source = inspect.getsource(module)
    lines = source.split("\n")
    num_lines = len(lines)
    if start_line > num_lines:
        return ""
    if end_line > num_lines:
        end_line = num_lines
    print("\n".join(lines[start_line:end_line]))

Within the eikon package there is a 'json_requests.py' module containing the function 'send_json_request'.

This request gets a response from calling a http_request method.
However, if this request fails it'll get response = None (say a timeout).

When try: logger.debug is called in the final line below it'll attempt to reference the status_code attribute of None and throw an attribute error.

In [21]:

show_source_code(ek.json_requests, 84, 94)

            # build the request
            udf_request = {'Entity': {'E': entity, 'W': data} }
            logger.debug('Request:{}'.format(udf_request))
            response = profile._desktop_session.http_request(url=profile.get_url(),
                                                             method="POST",
                                                             headers={'Content-Type': 'application/json',
                                                                      'x-tr-applicationid': profile.get_app_key()},
                                                             json=udf_request)
            try:
                logger.debug('HTTP Response code: {}'.format(response.status_code))

In [23]:

None.status_code

This sent me on a bit of a hunt for the underlying issue... I'll spare you the steps inbetween, but I ended up having to fiddle with the timeout variable in the nest_asyncio.py dependency.

In [27]:

import nest_asyncio

In [32]:

show_source_code(nest_asyncio, 71, 74)

        timeout = 0 if ready or self._stopping \
            else min(max(0, scheduled[0]._when - now), 10) if scheduled \
            else None

If left unaltered then we'll end up with the issue you're seeing.

In [1]:

APP_KEY = "..."

In [2]:

import eikon as ek

ek.set_app_key(APP_KEY)

In [3]:

ek.get_news_headlines("AAPL.O",count=10)

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

    119         payload.update({'dateTo': to_datetime(date_to).isoformat()})
    120 
--> 121     result = eikon.json_requests.send_json_request(News_Headlines_UDF_endpoint, payload, debug=debug)
    122 
    123     if raw_output:

     92                                                              json=udf_request)
     93             try:

     95                 logger.debug('HTTP Response: {}'.format(response.text))
     96             except UnicodeEncodeError as unicode_error:

AttributeError: 'NoneType' object has no attribute 'status_code'

And that's what I was seeing...

However, we can modify the code in nest_asyncio and it'll work. Yes, it's a hack, but it'll work until the devs clean things up.

I incremented the timeout as follows (by adding 3 extra lines at the end):

In [9]:

import inspect
import nest_asyncio

show_source_code(nest_asyncio, 71, 77)

        timeout = 0 if ready or self._stopping \
            else min(max(0, scheduled[0]._when - now), 10) if scheduled \
            else None
        if timeout is not None:
            if timeout > 0:
                timeout = 20

And if you try it again:

In [4]:

ek.get_news_headlines("AAPL.O",count=1)
