# Serverless Framework and Serverless Offline Error: POST Request Not Responding

I recently upgraded my development workflow for serverless functions to include using a Docker container that hosts the [Serverless Framework CLI](https://www.serverless.com/framework/docs/getting-started/). I didn't pay much attention to versions when I built the Dockerfile and selected the latest NodeJS base image, which is NodeJS version 16. When I began testing a new POST HTTP endpoint I would never receive a response, just waiting and waiting. 

After much debugging and a successful search I found that there is a known [issue](https://github.com/dherault/serverless-offline/issues/1150) with the Serverless Framework and the [Serverless-Offline](https://www.npmjs.com/package/serverless-offline) plugin when hosted on a NodeJS version 15.4X or higher. POST requests will fail to respond or resolve.

**The Fix**: Downgrade NodeJS version, NodeJS 14.X upto 15.14 has been successfully tested.
