Celery has started throwing errors

[ericsoco]

Not sure what is going on, but now every time I try to load shapefiles (same ones I've been using successfully previously for testing), celery throws errors like this:

Task tasks.run_topology[f11b2668-0566-496b-a0e9-41ec2c5d4b1d] raised unexpected: TypeError("argument of type 'NoneType' is not iterable",)

Therefore, I can't upload any more files for testing.

I noticed that you dropped the "barrier" input. Might be related to that?

[mojodna]

(though I did see it working...)

@brelsford any ideas?

[brelsford]

it looks like the problem is that the match_barriers function doesn't handle the case where there are no barriers at all in the input. (This is also the most typical case).

Hm, that might make sense. I dropped it at @saraedean's suggestion, since entering some values (not sure which are valid and which are not) can cause other errors. I can put it back in, perhaps there was a default value submitted previously.

@brelsford @mojodna that was the problem. Cleared the celery queue and added the Barrier Index input back in, and everything is running smoothly. Thanks!
