Token is not valid after success callback

[theone3nu]

I am able to get the token but when i use that token to generate refresh token it says { "error": "invalid_request", "error_description": "Unable to retrieve access token: appid/redirect uri/code verifier does not match authorization code. Or authorization code expired. Or external member binding exists" }

When i manually generate token using this https://www.linkedin.com/oauth/v2/authorization?response_type=code&client_id=xxxxxxx&redirect_uri=https://localhost:3000 that token is working fine.
