Unable to run a push queue task on Google Appengine with the Python27 SDK

Question

When trying start a simple push queue task on Google Appengine Python27 SDK (which ran fine on Python 2.5) I'm now getting a traceback ending with:

File "c:\program files\google\google_appengine\google\appengine\api\taskqueue\
   taskqueue_stub.py", line 1662, in ExecuteTask connection.putheader(header_key, header_value)

File "C:\Python27\lib\httplib.py", line 924, in putheader str = '%s: %s' % (header, '\r\n\t'.join(values)) 

TypeError: sequence item 0: expected string, int found

The TypeError above occurs for

header = 'Content-Length'

values = (112,) 

That should obviously be values=('112',)

Thankful for any advice,

Mort

Looks like a bug and it has been reported: Issue 6460: Development Server - taskqueue stub type error

To get it working you'll need to patch the SDK manually, file: google/appengine/api /taskqueue/taskqueue_stub.py , line which looks like:

headers.append(('Content-Length', len(task.body())))

fix to:

headers.append(('Content-Length', str(len(task.body()))))
