Probably better to ask on the QGIS developer or users list - hopefully
the plugin authors are subscribed and can help you.

You could just wrap that statement in a try except block like this

zoom = 1
try:
    zoom = np.abs((np.array(zooms) - scale)/scale)
except:
    return


Note I havent looked at the code so have no idea if that will produce
a reasonable outcome.
