internal server error- tried to follow the suggested solutions but cannot really proceed

Dear Community, while I tried to set up serverless I encountered the following screen: https://b3pe6tfdal.execute-api.eu-central-1.amazonaws.com/dev/api/get-auth-url I am fairly new to serverless and AWS therefore I have been trying to reach anyone who could rather better understand explain what might not be working. I created a OAuth consumer and it seems to be find. I set up serverless the following way: npm install -g serverless serverless create --template aws-nodejs --path auth-server cd auth-server npm init Afterwards I created a key, downloaded and executed: serverless config credentials --provider aws --key ACCESS_KEY_ID --secret SECRET_ACCESS_KEY (I did replace the examples-Access_Key_id & Access_key). Now if I run this URL: https://accounts.google.com/o/oauth2/v2/auth?access_type=offline&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcalendar.readonly&response_type=code&client_id=MY_CLIENT_ID&redirect_uri=https%3A%2F%2Fherra17.github.io%2Fmeet%2F

I get this-> https://herra17.github.io/meet/?code=4/0AVHEtk7XivdkSnIIzX9SMhFXBtPCvbXYExk8PpDA-sE1mtG4HxiYz-Wp6j6Fn1ls2FKCog&scope=https://www.googleapis.com/auth/calendar.readonly (I am not sure that I can share a screen). Know locally if I do serverless invoke local --function getAuthURL I get: { "statusCode": 200, "headers": { "Access-Control-Allow-Origin": "*", "Access-Control-Allow-Credentials": true }, "body": { "authUrl": "https://accounts.google.com/o/oauth2/v2/auth?access_type=offline&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcalendar.readonly&response_type=code&client_id=MY_CLIENT_ID&redirect_uri=https%3A%2F%2Fherra17.github.io%2Fmeet%2F" } }, as well if I test it in Lambda console: I get a status of 200, serverless info returns service: auth-server stage: dev region: eu-central-1 stack: auth-server-dev console: https://console.serverless.com/herra17/metrics/awsLambda?globalEnvironments=dev&globalNamespace=auth-server&globalRegions=eu-central-1&globalScope=awsLambda&globalTimeFrame=15m endpoints: GET - https://b3pe6tfdal.execute-api.eu-central-1.amazonaws.com/dev/api/get-auth-url GET - https://b3pe6tfdal.execute-api.eu-central-1.amazonaws.com/dev/api/token/{code} functions: getAuthURL: auth-server-dev-getAuthURL getAccessToken: auth-server-dev-getAccessToken, Anyhow the endpoint for the get-auth-url throws me the internal server error. Specifically a screen with : //numbers which I am not sure they represent important data // https://b3pe6tfdal.execute-api.eu-central-1.amazonaws.com/dev/api/get-auth-url

{ "message": "Internal server error" }

I have tried to follow along the following Resource but I do not seem to have the Monitor option under the selected HTTP API, hence I can not proceed. https://docs.aws.amazon.com/apigateway/latest/developerguide/http-api-troubleshooting-lambda.html Any thoughts I am using Node.js, Express as Lambda, React.
