This is honestly just good etiquette, and is also true for the Fediverse and Bluesky. Open source in general, really.

Being able to write a good issue for a repo's tracker is crucial. You need context: what steps did you take to make it happen? Can you recreate it? If there was an error message, either in a GUI or a terminal, what was it? What was your OS / browser setup? Did you have to use something specific to get the app to work on your device, like Homebrew?

It can become kind of a rabbit hole of "What info do I need to bring with me?", but any supportive information is better than nothing.
