Unable to parse query string

[codewriter3000]

Describe the bug

When I try to authorize, I get an error that says "Error; invalid request, unable to parse query string" To Reproduce

1. Register an application as such:
2. Create a code_challenge as such:

   
   import random
   import string
   import base64
   import hashlib

code_verifier = ''.join(random.choice(string.asciiuppercase + string.digits) for in range(random.randint(43, 128))) code_verifier = base64.urlsafe_b64encode(code_verifier.encode('utf-8'))

code_challenge = hashlib.sha256(code_verifier).digest() code_challenge = base64.urlsafe_b64encode(code_challenge).decode('utf-8').replace('=', '')

print(fr'code verifier: {code_verifier}') print(fr'code challenger: {code_challenge}')

3. Go to: http://127.0.0.1:8000/o/authorize/?response_type-code&code_challenge=YO1xUfYUKR6PCM5m3r-IjQWJKbhQ8YgMls8gigtnVxc&code_challenge_method=5256&client_id=2edYoWkN7DBj6uREFbvjnbJLrN3Hzr64G7dxH0wL&redirect_uri=http://127.0.0.1:8000/noexist/callback and set the proper parameters.

It looks like response_type-code should be response_type=code and the redirect_uri should be url encoded. please re-open if that doesn't resolve your isssue.

The error is now Mismatching redirect URI
