Cognito - error: OAuth2RequestError: invalid_client

[timootten]

Hey, there is an error when using this:

const tokens = await amazonCognito.validateAuthorizationCode(code, codeVerifier);

Error:

OAuth2RequestError: invalid_client

The problem: aws doesn't support http basic auth.

Solution:

try {
        const urlParams = {
            grant_type: "authorization_code",
            code,
            redirect_uri: "http://localhost:3000/api/auth/callback/cognito",
            code_verifier: codeVerifier,
        }
        const URL = `${(process.env.AUTH_COGNITO_URL ?? "")}/oauth2/token?${new URLSearchParams(Object.entries(urlParams)).toString()}`;

        const body = {
            client_id: process.env.AUTH_COGNITO_ID ?? "",
            client_secret: process.env.AUTH_COGNITO_SECRET ?? ""
        }

        const response = await fetch(URL, {
            method: "POST",
            headers: {
                'Content-Type': "application/x-www-form-urlencoded",
            },
            body: new URLSearchParams(Object.entries(body)).toString()
        })

        const json = await response.json();

        console.log("json", json)
    } catch(error) {
...
}
