wm.get_sample_sets() function is returning an error

[sabrinacamp2]

Hi,

I have been receiving errors when attempting to retrieve the sample set table from the data model. This function worked for me last week. For clarity this is the full code I used to return a sample set:
wm = dalmatian.WorkspaceManager('vanallen-firecloud-dfci/ogct_germline_analysis')
sampleset = wm.get_sample_sets()

This is the error I receive:

TypeError: ("argument of type 'int' is not iterable", 'occurred at index scatterIndices')

Any help would be greatly appreciated. I love your tool and use it daily!

All the best,
Sabrina
