Hello, I’m trying to integrate TypeORM and typeorm-aurora-data-api-driver with SST. Right now I’m getting

Function

...
const api = new sst.Api(this, "Api", {
      routes: {
        "GET /": {
          function: {
            handler: "src/function/db.handler",
            environment: {
              DATABASE,
              CLUSTER_ARN: cluster.clusterArn,
              SECRET_ARN: cluster.secret!.secretArn,
            },
            bundle: {
              esbuildConfig: {
                plugins: "./esbuild-config.js",
              },
              nodeModules: ["typeorm", "typeorm-aurora-data-api-driver"],
            },
            permissions: [cluster],
          },
        },
      },
    });

tsconfig.json

{
  "compilerOptions": {
    "experimentalDecorators": true
  },
  "extends": "@tsconfig/node14",
  "include": [
    "stacks",
    "src"
  ]
}

Any help would be appreciated.

You probably need to emit metadata from your decorators too.

/* Experimental Options */
    "experimentalDecorators": true,           /* Enables experimental support for ES7 decorators. */
    "emitDecoratorMetadata": true,            /* Enables experimental support for emitting type metadata for decorators. */

@Adam Fanello silly me 🤦‍♂️ “emitDecoratorMetadata”: true, did the trick. Thank you!
