[Python] Variable not assigned within except block [closed]

Try-except-finally block won't assign a variable within the except block:

if "access_token" in result.keys():
print("Successful token acquisition from:", result["token_source"]) # Since MSAL 1.25
# Calling a web API using the access token
r = requests.get(
queryURL,
headers={'Authorization': 'Bearer ' + result['access_token'], 'Prefer':'odata.include-annotations="OData.Community.Display.V1.FormattedValue"'},
)
t = r.text
api_result = r.json()
try:
query = api_result['value']
except KeyError:
(THIS LINE) query = api_result
if 'error' in api_result:
err_code, err_msg = api_result['error'].items()
raise DataverseError(err_code, err_msg)
raise NoValuesBlockError(api_result.keys())
finally:
return query
else:
raise TokenAcquisitionError(value=result)


api_result.keys() =
dict_keys(['@odata.context', '@odata.type', 'ParentOptionSetName', 'IsCustomOptionSet',
'IsGlobal', 'IsManaged', 'Name', 'ExternalTypeName', 'OptionSetType', 'IntroducedVersion',
'MetadataId', 'HasChanged', 'Options', 'Description', 'DisplayName', 'IsCustomizable'])


but query isn't assigned to api_result in the highlighted line.

There is a case where there will be no values block, nor an error block, that should be caught and still returned.
