invalid_client error when signing in with AWS Builder ID

[msbeeman]

Problem

When attempting to sign in with the builder ID through VS Code, am always getting a 'invalid_client' during the authentication process.

Troubleshooting

I've tried:

• Deleting browser cache
• Reinstalling VS Code completely including deleting the application cache
• Tried the SSO code step on another device (phone) and still received same invalid_client response.
• Tried deleting current AWS builder account and creating another one with a different email, same behavior.

Steps to reproduce the issue

1. Go to Developer Tools in VS Code

2. Click on CodeWhisperer

3. Click Start

4. Click on 'Sign up or Sign in:

   

5. Copy Code and Proceed

   

6. Re-directed to https://device.sso.us-east-1.amazonaws.com/ and asked to enter code

8. Enter in code

9. See error received 'invalid_client'.

10. Network tab shows 401 unauthorized response. Client ID in the 401 unauthorized response seems to be different than the client ID in the authorize request. Noticed the request clientId seems to start with 'Vjhfek...' while the unauthorized response clientId seems to start with 'V8_z...'

Expected behavior

For the sign in to work and be able to enable code whisperer.

Fix was to delete the hidden Home/AWS/SSO folder, old cached credentials in there.
