What is the significance of the NS_ERROR_UNKNOWN_PROTOCOL error code?

When attempting to make an AJAX request using Angular 1.5.9, my code is as follows:

$http.get('localhost:8080/app/users').then(function(resp) { ... });

However, I am encountering an error that reads:

"NS_ERROR_UNKNOWN_PROTOCOL" (...) stack: "createHttpBackend/<@http://localhost:8080/app/libraries/angular.js:12115:5 ..."

Interestingly, the URL is valid and accessible via the browser.

Answer №1

When manually entering localhost:8080/app/users into the browser, it automatically adds the prefix http:// which is not included in this case. This is why the error message states "unknown protocol".

The correct URL should be http://localhost:8080/...
