pbs add_tasks fails with TypeError

[christopherthomson]

Thanks for creating the pbs command line tool. I'm trying to follow the Pybossa tutorial but get a type error at the add_tasks step. It looks like one of the variables in the _pybossa_req function is returning None. I get the same result using the sample JSON file from the Pybossa tutorial, and the same result again after creating this file by running the get_images.py script.

Here is the traceback:

Thanks.

Hi,

Thanks for reporting this issue. We just released a new version yesterday, would you mind to tell us which version do you have in your system?

[christopherthomson]

I should have included this first up. pbs version is 2.4.0:

(pybossa-env)vagrant@vagrant-ubuntu-trusty-64:/vagrant$ cd app-flickrperson/
(pybossa-env)vagrant@vagrant-ubuntu-trusty-64:/vagrant/app-flickrperson$ pbs version
2.4.0

I set up the VM using instructions here.

Ha, I've just tested a new install with my own data set and it works. Would you mind to share some data so we can test it?

Hi, I'm using the flickr_tasks.csv file that comes with the tutorial app. I think they're images from your flickr account! I also tried the get_images.py script which creates a json file but this also gives the same error. Do the strings in the CSV need to be wrapped in quotes perhaps?

Further info:
I'm using Ubuntu 14.04.5 LTS (GNU/Linux 3.13.0-119-generic x86_64) running in a VM using Vagrant 1.9.2 and VirtualBox Version 5.1.22 r115126 (Qt5.5.1). The host machine is Ubuntu 16.04.

I just upgraded pbs (pip install --upgrade pybossa-pbs) to version 2.4.2, but get the same error upon running the add_tasks command:

File "/home/vagrant/pybossa-env/local/lib/python2.7/site-packages/pbclient/init.py", line 38, in _pybossa_req
url = _opts['endpoint'] + '/api/' + domain
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

I have it working now. I created the config file at ~/.pybossa.cfg and now things work. I got the impression this step was optional but may have misread. Thanks for your help!

Then it looks like you have found a bug. We all use the pybossa.cfg file, so maybe that's why we are not seeing that bug. I'll try to replicate it.
