Failed to add package

[LuisCPi]

• I have searched the issue tracker and believe that this is not a duplicate.

Steps to reproduce

Trying to add pytest as a package to the project to: "pdm add -d pytest"

For some reason it doesn't recognize the "billiard" dependency inside the celery package

Actual behavior

Result:

Adding packages to dev dev-dependencies: pytest
See /tmp/pdm-lock-lpqntqlj.log for detailed debug log.
[TypeError]: a bytes-like object is required, not 'str'

Detail result:

Package detail:

[[package]]

version = "4.4.7"
requires_python = ">=2.7, !=3.0.*, !=3.1.*, !=3.2.*, !=3.3.*, !=3.4.*"
summary = "Distributed Task Queue."
dependencies = [
    "billiard<4.0,>=3.6.3.0",
    "kombu<4.7,>=4.6.10",

    "vine==1.3.0",
]

Expected behavior

I hope the package is installed successfully
