AWS-LAMBDA：没有这样的文件或目录，打开'./src/graphql/schema.graphql'

Question

I am practicing Graphql and AWS. I used simple serverless framework also create simple Graphql schema. I deployed the schema(seems like this graphql.schema file does not deploy), resolvers to AWS. It successfully create a DynamoDB table and lambda. I can able make POST/GET request via Graphql Playground by using serverless-offline. But the issue is the the api end-point does not work. It's show me internal server error . I was investigating the issue. From cloud watch I found the local schema which I created the Lambda function did find the graphql.schema . This is the error I am getting "ENOENT: no such file or directory, open './src/graphql/schema.graphql'". This is the lambda error Image

This is my lambda function

 import { ApolloServer } from 'apollo-server-lambda'; import { ApolloServerPluginLandingPageGraphQLPlayground } from 'apollo-server-core'; import runWarm from '../utils/run-warm'; import fs from 'fs'; const schema = fs.readFileSync('./src/graphql/schema.graphql', 'utf8'); // This is local my schema import resolvers from '../resolvers'; const server = new ApolloServer({ typeDefs: schema, resolvers, introspection: true, plugins: [ApolloServerPluginLandingPageGraphQLPlayground()], }); export default runWarm( server.createHandler({ expressGetMiddlewareOptions: { cors: { origin: '*', credentials: true, allowedHeaders: ['Content-Type', 'Origin', 'Accept'], optionsSuccessStatus: 200, }, }, }) );

This is my serverless YAML file

As you observed, the ./src/graphql/schema.graphql isn't being packaged to the final artifact Serverless builds and deploys.

You can add it by specifying the package property to your function:

graphql:
  handler: src/handlers/graphql.default
  events:
    - http:
        path: ${env:api_prefix}/graphql
        method: any
        cors: true
  package:
    include:
      - src/graphql/schema.graphql
