I have the following error in the Chrome Dev Tools console on every page-load of my Node/Express/React application:
Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist
This error makes a reference to localhost/:1. When I hover over this, it shows http://localhost:3000/, the address I’m viewing the app at in the browser.
Anyone have an idea what is going on? Most of the other threads I’ve found that bring up this error seem to be related to someone trying to develop a Chrome Extension, and even then they tend to have very few responses.
