I am getting the error "Browser requests to the token endpoint must use Proof Key for Code Exchange" when trying to post the following request from my code. But the same is working from the postman. Am I missing anything here?

  const urlEncodeData = qs.stringify({
            grant_type: "client_credentials",
            client_id: "xxxxxxxxxxxx",
            client_secret: "xxxxxxxxxxxxx",
            scope: Scope,
        });
        const headers: any = {
            "Content-Type": "application/x-www-form-urlencoded",
          
        };

        const tokenData = await axios.post(
            `${issuer}/v1/token`,
            urlEncodeData,
            headers
        );

I tried using qs and urlsearchparams and nothing worked.
