IndexError: list index out of range

Hi,

I only want to create teiHeader.
The example works:
mm2tei "https://digital.slub-dresden.de/oai/?verb=GetRecord&metadataPrefix=mets&identifier=oai:de:slub-dresden:db:id-453779263"
But my data always gives the following error-message.

(env) mm2tei bsb00000002_mets.xml
Traceback (most recent call last):

In line 148 of mets_mods2tei/api/mets.py:

            roles = name.get_role()[0].get_roleTerm()

Replace this with

            roles = name.get_role()[0].get_roleTerm() if name.get_role() else []
