An assertion error has been thrown stating that the host should not be left empty when using a proxy in expressjs

Upon attempting to run my expressjs project, I encountered errors such as an AssertionError stating that the host should not be empty at proxy (index.js:27:3). The npm log also displays error codes including ELIFECYCLE and errno 1. Additionally, there is a failure message related to the start script.

For more details on this issue, please refer to the complete log located in /home/folder/.npm/_logs/2020-01-01T07_03_08_044Z-debug.log

Answer №1

The proxy in your app, which is powered by express-http-proxy, requires a value as its first argument. However, this value appears to be missing or undefined.

Review all instances of the proxy function within your application to pinpoint the location where the argument is missing. It's likely that you have specified this value and are retrieving it from an .env file, but it has not been defined within the .env file itself.
