Description should be language-agnostic.

It's not an error, it's simply the title of a particular test group. What you're looking for is what is shown inside it.

"Should reach all nodes in a loop"
What does this error mean?

There is no such test case. Probably you were mutating the input.

This kata needs better tests, some examples have multiple valid paths.
Given miner M, exit E and open path 0:

both [right, down] and [down, right] are valid paths
M 0
0 E

# both [right] and [down, right, up] are valid paths 
M E
0 0

It was an issue 7 years ago, other people reported similar problems - server-side tests (I guess node.js) were handling the copying/cloning not the same way chrome was doing it.

The tests may be working fine, but they work (at least worked) differently in different interpretators.

It's not issue with my code. I've reported that my code produces different outputs when it's run in browser and on your server.

Closing it like this 7 years later is just rude.

Good thing I'm not investing my time into this website anymore.

issue with your code is not an issue, read this

Issue with your code is not an issue, JS's tests work fine

I've done several 4kyu katas that were easier than this one. Also, the requirements are terribly illogical.

Ruby 3.0 should be enabled.

Very strange choices :

1. map (not the best name choice in Python) is given by rows (?!)
2. coordinates (x, y) are not defined and correspond to a very unusual (col, row)
3. start and goal positions are given by a dictionary (?)
