Call to token endpoint is failing to get Access Token for webapp

[Rahul-0108]

I am trying to get id_token and access token for webapp registered in developer.bentley.com , but getting error . I am able to get code from authorization endpoint but the call to token endpoint is failing.This is how I am making the call to token endpoint :

const tokenResponse = await axios.post(
"https://imsoidc.bentley.com/connect/token",
{
grant_type: "authorization_code",
client_id: this.provider.client_id,
code: this.provider.code,
code_verifier: this.provider.code_verifier,
redirect_uri: "http://localhost:5000/signin-oidc",
},
{ headers: { "content-type": "application/json" } }
);

}

Take a look at: https://developer.bentley.com/apis/overview/authorization/
Try posting to https://ims.bentley.com/connect/token; grant_type = authorization_code looks right

Hi , getting the tokens from /token endpoint worked after following the documentaion : https://developer.bentley.com/apis/overview/authorization/ .Now , I am facing issue for logout functionality , I added a post logout redirect url while registering the webapp . There is no logout endpoint mentioned in the API documentaion . I assume it to be https://ims.bentley.com/connect/endsession which I got from the https://ims.bentley.com/.well-known/openid-configuration url .
This endpoint logs out the user but does not redirect to my post logout redirect uri . This is how I am making the call : https://ims.bentley.com/connect/endsession?redirect_uri=http://localhost:5000

Could you try post_logout_redirect_uri instead of redirect_uri ?
So it'd be https://ims.bentley.com/connect/endsession?post_logout_redirect_uri=http://localhost:5000
