Module not found: Error: Package path . is not exported from package

[lBroth]

Describe the bug
I encountered the following error:
Module not found: Error: Package path . is not exported from package node_modules/@middy/core (see exports field in node_modules/@middy/core/package.json).

To Reproduce
In my tsconfig.json file, I set the following configuration:

"module": "commonjs",
"moduleResolution": "node"

This issue arises when using TypeScript version 4.8.4 in conjunction with webpack.

Expected behavior
I resolved the problem by applying the following patch to the package.json file of the @middy/core module:

diff --git a/node_modules/@middy/core/package.json b/node_modules/@middy/core/package.json
index fc07d5e..b38f5de 100644
--- a/node_modules/@middy/core/package.json

+        "types": "./index.d.ts",

        }
     }
   },

Environment:

• Node.js: [18]
• Middy: [5.0.3]

Thanks for reporting and suggesting a fix.

As announced over a year ago, CommonJS is no longer supported with the latest release, v5. AWS Lambda can run ESM natively and benchmarks show it out performs CJS. So, updating is recommended. If you need CJS support, v4.x is an option (currently has no reported security vulnerabilities).
