Describe the bug

Version 1.3.1 changed how JsonParseNode behaves on a string containing a single slash at the start or the end.
Before this version try_get_anything returned the input value, on 1.3.1 an exception is raised.

To Reproduce

The simple test that can be added to tests/test_json_parse_node.py

def test_get_anything_does_work_on_single_slash():
    parse_node = JsonParseNode("/2")
    result = parse_node.try_get_anything("/2")
    assert isinstance(result, str)
    assert result == "/2"

Expected behavior

Exception should not be raised and the input value should be returned.

Screenshots

Additional context

I've encountered this issue when using Microsoft Graph API via msgraph.GraphServiceClient

[czaroPieczaro]

Also got that error. Thanks for raising it.

[wiget]

Re-tested against 1.3.2 - still failing to parse.

Is there any update on this issue?

The error comes from the pendulum library, there is also an issue in their repo: sdispater/pendulum#506
However, the issue is open since 4 years, and the maintainer didn't even respond to it or the attached PR.

I submitted the PR in pendulum to fix the bug: sdispater/pendulum#843
