Retrieve data with Uber Rides Python SDK fails with 500 error

Having followed this tutorial https://developer.uber.com/docs/riders/ride-requests/tutorials/api/python , I'm getting errors when trying to fetch data such as user profile or activity.

Here is my sample(Flask) code:

import os
from datetime import datetime
from flask import Flask, request, flash, url_for, redirect, \
     render_template, abort, send_from_directory, redirect

from uber_rides.auth import AuthorizationCodeGrant
from uber_rides.session import Session
from uber_rides.client import UberRidesClient

app = Flask(__name__)
app.config.from_pyfile('flaskapp.cfg')

# Configure Uber Oauth2.0
auth_flow = AuthorizationCodeGrant(
    '<client_id>',
    ['profile', 'history'],
    '<client_secret>',
    'http://localhost:8080/callback'
    )

@app.route('/')
def index():
    auth_url = auth_flow.get_authorization_url()
    return redirect(auth_url, code=302)

@app.route('/callback')
def callback():
    session = auth_flow.get_session(request.url)
    client = UberRidesClient(session)
    credentials = session.oauth2credential

    # Fetch users profile
    response = client.get_user_profile()
    profile = response.json

    first_name = profile.get('first_name')
    last_name = profile.get('last_name')
    email = profile.get('email')

    # Fetch user activity
    response = client.get_user_activity()
    history = response.json

    return first_name, 200

if __name__ == '__main__':
    app.run(debug=True)

And trace of errors:

Could this be a problem with Uber's service?

Update 3: I have dug into the rides_python_sdk and added extra headers as shown in the docs https://developer.uber.com/docs/riders/ride-requests/tutorials/api/curl#get-a-list-of-products-available

I also corrected the Accept-Encoding param to what is in the sdk ['gzip, deflate']

Still getting the 500 error

Solution

  • Thanks for your patience while I investigated this issue. This was an underlying bug in our v1 oauth endpoints which impacted newly created applications. I have released a new version of the sdk that resolves this problem. Please use v0.4.0 and you should not have any issues. Thanks for the detailed feedback!
