Passing bytes to tomllib.loads() gives wrong error message #132655
Description
Bug report
Edit: It looks like this was fixed in #124587 but either regressed or that hasn't been released yet? It was merged October 2024.
Bug description:
If you call tomllib.loads() and mistakenly pass in a bytes object instead of a string...
tomllib.loads(b'a="asdf"')...you get a TypeError as expected, but the error message is wrong:
TypeError: a bytes-like object is required, not 'str'
The error message should be the reverse, something like "a string-like object is required, not 'bytes'".
The bug is present on macOS with the following versions:
- 3.13.3
- 3.12.10
- 3.11.12
CPython versions tested on:
3.13, 3.12, 3.11
Operating systems tested on:
macOS

This should be closed, the problem is an update was not backported (it only works on 3.14) as it is a semi-bug/feature, if we want to backport it discussion should be moved to the original issue #124835.
Backporting would only go as far as 3.13, there is nothing to do for other versions.

@picnixz Any thoughts -- should it be backported?

I'd intentionally chosen not to backport as per #124835 (comment)

This can be closed then :-)

Got it, makes sense. Thanks for the quick response as well.
