Failed to export to PDF

[Misha-Sybrid]

Getting the following error when script is finishing its job:
url = cURL + "/wiki/" + url
~~~~~~~~~~~~~~~~^~~~~
TypeError: can only concatenate str (not "NoneType") to str

I believe it comes from the failure of finding the task ID:
['', '', ' Task Not Found', ' Task Not Found', ' 0', ' 0', ' 100', ' false', ' true', '', '']

this is the output after the split on task_id parameter on line 142:
task_id = response_string.split('name="ajs-taskId" content="')[1].split('">')[0]
