Hello, I have created a Stack using the GraphQLApi construct, and I linked my lambda function in the “server” property. This lambda function, has an async handler. The problem is that when i run it in debug mode, the following error is thrown:

08581965-f277-4f60-9210-d7f52227e4b7 ERROR TypeError: The first argument must be of type string or an instance of Buffer, ArrayBuffer, or Array or an Array-like Object. Received undefined

I suspect that this is because I made the function endpoint async, is that possible? Thanks

Hey what version of sst are you on

Hey, this is the output:

SST: 1.2.15

CDK: 2.24.0

Hey @Bruno Give this Apollo example a try. https://serverless-stack.com/examples/how-to-create-an-apollo-graphql-api-with-serverless.html

Thanks, I figured it out, it was the way I called the createHandler function of ApolloServer that was incorrect
