error using updatewcs

I'm running into an error with updatewcs where it seems to start running and then exits with a TypeError. I'm running this in an AstroConda python 3 environment, running stwcs v1.4.0. Any tips on how to proceed would be appreciated.

This is the error message:

TypeError Traceback (most recent call last)

121 # an accessible astrometry web-service

    There were updates to the software that now require an additional parameter.
    We are trying to document this more clearly to users:

    Try using this command and let us know if it solves the problem.

    updatewcs.updatewcs('*flc.fits', use_db=False)

    Thanks, this did solve the problem.

    I reported this to the software developer and it turns out to have been a bug.
    A fix is in the works, so you shouldn't have to do this in the future.
