resolve_pointer raises an unhandled JsonPointerException when traversing an OrderedDict and encountering a missing key — reported when sphinx-jsonschema processes JSON Schema files containing OrderedDict-backed documents.

Changes

  • tests.py: Import OrderedDict; add test_ordereddict_member_not_found to WrongInputTests — constructs an OrderedDict mirroring the schema from the issue report and asserts JsonPointerException is raised when resolving a pointer to a non-existent member.
doc = OrderedDict([
    ('$schema', 'http://json-schema.org/draft-07/schema#'),
    ('$id', '/sports_field'),
    ('type', 'object'),
    ('properties', OrderedDict([...])),
])
# Raises JsonPointerException: member 'src' not found in OrderedDict(...)
resolve_pointer(doc, '/src')
Original prompt

<issue_description>I am trying to document schema files using sphinx.
Once I add the file path it throws this error

    raise JsonPointerException("member '%s' not found in %s" % (part, doc))
