The function that gets called when you click the Deploy button is here: [https://github.com/node-red/node-red/blob/82677c304e7640a5ea640bac407eb7ac719d6c78/packages/node\_modules/%40node-red/editor-client/src/js/ui/deploy.js#L322](https://github.com/node-red/node-red/blob/82677c304e7640a5ea640bac407eb7ac719d6c78/packages/node_modules/%40node-red/editor-client/src/js/ui/deploy.js#L322)
You can step through that function to see how it checks what it is about to deploy.

What steps exactly have you done?
Are you rebuilding the editor code when you change it?

How are you running Node-RED?
I assume because you didn't say so that you are _not_ running a proper build after modifying the code?
You need to run `grunt build` after modifying the source code so it can be built into the `red.js` file the editor loads.
Another option is to use the `grunt dev` task - this runs node-red itself and watches for any changes to the source code, automatically restarting Node-RED or rebuilding the editor code as needed.
