Python inspector cannot resolve azure-devops dependency

[nnobelis]

I have the following requirement.txt file:

azure-devops
azure-storage-blob
click

If I run:
python-inspector --python-version 310 --json-pdt - --requirement requirements.txt --verbose

it crashes:

If I replace the first line with
azure-devops==6.0.0b4

it is successful.

Why a version is required for azure-devops and not the other ones ?

Also for information, here was the result found with pipdeptree :

Why pipdeptree found the version b2 when the version b4 was available ?
