Fixed, thanks for pointing that out

Are you certain you're looking at the correct log, and not the previous or the next testcase?

Ok so how it's possible that this:
[[[1,3,2,5,7,9,4,6,8],
[4,9,8,2,6,1,3,7,5],
[7,5,6,3,8,4,2,1,9],
[6,4,3,1,5,8,7,9,2],
[5,2,1,7,9,3,8,4,6],
[9,8,7,4,2,6,5,3,1],
[2,1,4,9,3,5,6,8,7],
[3,6,5,8,1,7,9,2,4],
[8,7,9,6,4,2,1,3,5]], true]

  is true????????? it has repeated 3's on the eight column and repeated 5 on the 9 column.

Reading the docs: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replaceAll#browser_compatibility

Now it works fine, thanks. But how I was supposed to know that lol?)))

My solution passed all the tests, although it shouldn't have.

LC translation

this translation modifies the description
JS tests have been reused verbatim
number of tests has been reduced for performance reasons ( and even then, it's close, very close, to 12 seconds )

I always add translations and make edits with forks, only some very minor issues (like typos) directly with code editor.
I usually also approve (or self-approve, since I am technicaly the author) languages I am somewhat confident with. But I plan to add at least as many languages as were there in the retired kata, and I am not too familiar with many of them, so If I create translations for them, I will probably leave them for review.

The problem has been solved, but you will not see the changes on your computer unless you first save your code somewhere, and then hit the 'RESET' button (this will erase what you have coded so far, hence why you should save it).

actual, expected are flipped in Java

Should be fixed.

I am not a native either, and I understand your struggle. What I was saying is that the sample test marked as valid is actually invalid.
Do you speak Russian by any chance?

But there is no "Z"

I am not an English speaker. Would you have a suggestion for better wording?

==> expected: true but was: false

This sample test is described as "valid BUT with 0s instead of 9s". That "but" renders the solution invalid, since the incomplete sudoku can't be considered solved.
It even says it in the task:

Boards containing one or more zeroes are considered to be invalid solutions.
