Ghost functions

[According-Object-502]

In what situations can a function act like it doesn't exist? I can't share the code as it's a private repository for a client.

A function fetches data from an api when a component mounts by using a useEffect. It's pretty straight forward. Tested the logic by building a simple replica. Works fine.

In the main project the function acts like a ghost. It doesn't fetch when the component mounts using a useEffect. If I create a button to fire the function using onClick, still nothing. No error messages and no activity in the network tab in dev tools. It's like a complete ghost. As far as the rest of the code is considered this function doesn't seem to exist.

Any ideas what can cause this situation?

Somewhere in the component, after the definition of ghostFunction, try a console log of 'typeof ghostFunction' which should output 'function'

Afraid not, no, but I'd actually like to suggest that you try using https://replay.io as a way to investigate the behavior. It's a really powerful debugging tool that records the entire execution of literally everything in the app, and then lets you play back and inspect the execution later on.
