bad or missing username when authenticating with Twitter

[casajavi]

Issue Description

I am trying to use the Twitter authentication through the Rest API and I keep receiving this error:

bad or missing username

I have set up the parse server with the necessary data as follows:

auth: {
   twitter: {
     consumer_key: "redacted",
     consumer_secret: "redacted"
   }
}

and I am sending a POST to /users with the following payload:

"authData": {
          "twitter": {
            "id": "12345678",
            "screen_name": "ParseIt",
            "auth_token": "redacted",
            "auth_token_secret": "redacted"
          }
        } 

I could not find any documentation detailing on how to achieve this and most of what I have tried has been from following the conversation on the PR by @flovilmart that added this functionality.

Maybe I am doing something wrong, if anyone has any suggestions I would appreciate it.

Steps to reproduce

The following command:

curl -X POST 
-H "X-Parse-Application-Id: redacted" 
-H "X-Parse-REST-API-Key: redacted" 
-H "X-Parse-Revocable-Session: 1" 
-H "Content-Type: application/json" 
-d '{
"authData": {
          "twitter": {
            "id": "12345678",
            "screen_name": "ParseIt",
            "auth_token": "redacted",
            "auth_token_secret": "redacted"
          }
        } 
}'

Expected Results

A new parse user should be created

Actual Outcome

The following error is thrown: bad or missing username

Environment Setup

• Server

  • parse-server version (Be specific! Don't say 'latest'.) : 2.5.3

• Database mLab, ObjectRocket, Digital Ocean, etc): mLab

Can you provide the logs when running with VERBOSE=1?

@casajavi I just had a look at the source code, and the only way to get 'bad or missing username' error is to neither provide authData nor a username on this POST /users

This probably means that the payload is malformed, I managed to get this:

url -X POST \
  -H "X-Parse-Application-Id: redacted" \
  -H "X-Parse-REST-API-Key: redacted" \
  -H "Content-Type: application/json" \
  -d '{"authData":{"twitter":{"id":"12345678","screen_name":"ParseIt","auth_token":"redacted","auth_token_secret":"redacted"}}}' \
  http://localhost:1337/parse/users
{"code":101,"error":"Twitter auth is invalid for this user."}

So I guess that's probably the way your payload is formed/malformed.

@flovilmart Ok I wasn't including the correctly formatted payload but yea now I get the error you get.

{"code":101,"error":"Twitter auth is invalid for this user."}

now I am in the same spot hahaha.... so why is this error happening ?

Is this suppose to create a new user or only link twitter to an existing user?

[flovilmart]

yeah so double check your auth_token, secret, and configuration. I believe there's an API explorer on twitter, so you can double check that all those parameters are valid.
