            In AWS Lambda using Node, can't get Express to work with aws-serverless-express
            Asked 2022-Mar-15 at 18:33

            Below is my sample code that is not working. No matter what I set up, I can't get Express to render my ejs page.

            Note: I have an API Gateway in front of the Lambda. That will only let in the traffic I want. Everything that hits my Lambda should have the express page rendered. While not in the code I am showing below, once working, I will do some validation and lookups before using express to show the page.

            I have built a test app using nestjs + Sequelize ORM + docker database (as of now local). As per documentation, I am using umzug library and AWS Lambda SAM template and triggering lambda handler. Below is the code for it. Connection Pooling is implemented to reuse existing sequelize connection. Below is the lambdaEntry.ts file where I trigger umzug.up() function. It is triggering but not migrating files.

            When done from command prompt node migrate up it works correctly. I am testing using sam invoke command to test it.

            It's 3 days i am on this problem of E2E tests on my GraphQL application with NestJS + Apollo / Express.

            When I am running my app with serverless offline or directly with my main file, it's working perfectly. I have my graph and all things I need :)

            But, when I am running E2E tests with Jest, I received an error from the await app.init() inside the beforeEach.

            After playing with the package.json and dependencies, the error throwed is TypeError: (0 , schema_1.makeExecutableSchema) is not a function.

            After many hours of intense programming ... I finally found the problem.

            Be careful if you use some "alias" for imports, because it can overwrite some of the packages used.

            Here, i use the @graphql alias, and it breaks all my tests. When I remove it, the problem disappear.

            TL;DR prefer the SDK's async-await patterns.

            Here is an example of consecutive async-await calls using the AWS SDK for JavaScript v3.*. Note the async keyword in the function signature and the await keyword before the promise-returning method calls. The docs have the complete client initialization code.

            ANSWER

            Answered 2022-Jan-28 at 10:12

            Your have a problem with your preflight request. A preflight request ist only sent by browsers and not by tools like Postman, so that is why the Postman request is still working.

            The preflight request is an OPTIONS request, so please check that you have an OPTIONS method in API Gateway for the path your are requesting, and check its configuration and that you for example aren't sending or expecting credentials with the OPTIONS request. Including credentials in a preflight request ist not allowed according to the Mozilla CORS Documentation.

            A reason why the request stops working after adding another path might be that you have made manual changes (perhaps regarding Authentication or CORS) to your API in the API Gateway Console. When you then push the same API with Amplify those changes are often overwitten. Please check that this isn't the case. And try to make all changes through the Amplify API (if you have created the API there) to avoid those problems.

            I've found the issue! I had set the ApiKey requirements for all the API Events.

            Since the OPTIONS request don't send any authentication header, the API Gateway refuses the request so the client won't ever see the correct OPTIONS response. I think that's a bug with SAM template/Cloudformation
