Use access token for API Gateway Authentication

[Mominadar]

Hi,

I am trying to OAuth as a custom authorizer for my AWS API Gateway APIs. The issue I am facing is that the access token I get is not a valid JWT token and so when I sent if over to API Gateway it cannot parse it to validate it. I am following the instructions here : https://auth0.com/docs/customize/integrations/aws/aws-api-gateway-custom-authorizers

I can get the access token by sending a request to token endpoint but that does not work on the browser. I need to be able to get it directly on browser so I can send requests from there since there is no backend for my application. Please help.

Note: user is successfully logged in and I get the id token and access token. The only issue is that the access token is not JWT and cannot be parsed for custom authorization.

I don't quite remember what was exactly needed for that.
But I do remember having to set the audience in case of Auth0 so that the access_token became a JWT.

{
    scope: 'openid profile email phone offline_access read:current_user',
    extraQueryParams: {
        audience: 'https://dev-fijd1e9x.us.auth0.com/api/v2/'
    }
}
