AttributeError: 'NoneType' object has no attribute 'endswith'

Question

I am currently working on a Python script that updates a web page. But running the main script generates this error:

<res status='-1'><error message="'NoneType' object has no attribute 'endswith'"><![CDATA[
Traceback (most recent call last):
  File "/path/to/file/ws_config.py", line XXXX, in Run
    tests = TestList().tests
  File "/path/to/file/ws_config.py", line XXXX, in __init__
    UpdateTestGroup(None),
  File "/path/to/file/ws_config.py", line XXXX, in __init__
    test = CT.CurlTest(settings),
  File "/path/to/file/config_tests.py", line XXXX, in __init__
    self.params.path = os.path.join('/', os.path.join(params.dir, params.file))
  File "/usr/lib/python2.6/posixpath.py", line 67, in join
    elif path == '' or path.endswith('/'):
AttributeError: 'NoneType' object has no attribute 'endswith'

I cannot past any code because is too long. What I am trying to understand is where the error lays or what part of the code is triggering the AttributeError. Can you please help me???

Answer 1

The path in the elif is a None and None == '' returns False so the remain will be executed. And backwards, the params.dir is a None. You need to check your code where the params.dir generated to see how the None come.
