Error in pheflux.getFluxes from tutorial.ipynb

When running section 3 of the Tutorial notebook (pheflux.getFluxes(inputFile,resultsDir,prefix_log_file,verbosity)), I receive the following error:

NameError: name 'DRBK' is not defined

I then removed the eval function so that tmp_constraint=field, but this resulted in another error:

NotImplementedError: Wrong number or type of arguments for overloaded function '_vertcat'.
  Possible prototypes are:
    _vertcat([Sparsity])

  You have: '((DM,str))'

This is probably due to my attempted fix, so I would appreciate any help in resolving this issue!
