_wait_for_job() Error

[PollyTikhonova]

This line is a cause of my error in _wait_for_job(jobid) function modelseed.py file: jobs = ms_client.call('CheckJobs', {})

While trying to get model from ModelSeed via API http://p3.theseed.org/services/ProbModelSEED/ (http://modelseed.org/about/version) I've got a error: Error creating models: Attribute (host) does not pass the type constraint because: Validation failed for 'Str' with value undef at constructor MongoDB::MongoClient::new (defined at /disks/patric-common/runtime/lib/perl5/site_perl/5.20.2/x86_64-linux/MongoDB/MongoClient.pm line 1069)

Looks like empty dict causes the problem, but I can't find any documentation at ModelSeed to repair this problem. Could you help me, please?
