@outofambit, I am working on FES for GSoC'21. I have made some changes to: fes_core.js, browser_errors.js.

This PR affects the part of my code that uses the report() function. This causes the checks on the PR by GitHub to fail even though the checks on my machine are passing(my fork is not updated).

How should I proceed so that the changes I make do not create problems in p5.js's main branch?

PR: #5305

hey @Aloneduckling sorry about that! i just pushed 63ce561 to your branch, which should fix the test failures. since i changed the underlying report(), i redirected everything internal to p5 to use the already existing p5._friendlyError() (similar to in this PR). you might need to update your branch from main, before you can merge but that should be all you need. lmk if you have any questions, i'm happy to help!
