tvdb_api 3.1 still has "ImportError: cannot import name '_to_bytes' from 'requests_cache.backends.base'" bug

[frank42hh]

          Hi, I'm unsure why this still doesn't work here, so any hint appreciated.

I'm on a Manjaro system (22.0.0, Codename Sikaris) and installed via pacman:

To install (1):
  python-cattrs          22.2.0-2  (Required By: python-requests-cache)  community
To build (4):
  python-url-normalize   1.4.3-16                                        AUR
  python-requests-cache  0.9.7-1                                         AUR
  python-tvdb_api        3.1-1                                           AUR
  tvnamer                3.0.4-1                                         AUR

So, If I understand this thread correctly, _to_bytes is gone in requests-cache 0.9.7 but this is fixed in tvdb_api 3.1-1.

Nevertheless, I still get the same error:

ImportError: cannot import name '_to_bytes' from 'requests_cache.backends.base' (/usr/lib/python3.10/site-packages/requests_cache/backends/base.py)

And it seems that this has NOT been fixed in 3.1.0:

[freddy@hades ~]$ grep -E '__version|_to_bytes' /usr/lib/python3.10/site-packages/tvdb_api.py
__version__ = "3.1.0"
from requests_cache.backends.base import _to_bytes, _DEFAULT_HEADERS
    key.update(_to_bytes(request.method.upper()))
    key.update(_to_bytes(url))
        key.update(_to_bytes(body))
                    key.update(_to_bytes(name))
                    key.update(_to_bytes(value))

So, what's going wrong here? Did I miss something?

One year later, I would like to ask how this still can be an issue. Is there a "secret bugfix" I didn't detect yet or does no one bother that this awesome tool doesn't work anymore?

Current trace:

And then:

Any suggestion on how to make this work again is highly appreciated.
