Metaphlan3 to graphlan

I wanted to ask for help with Galaxy module (Galaxy) of GraPhlAn. When trying to Annotate tree on a file (guide.txt) taken from here (graphlan · biobakery/biobakery Wiki · GitHub), the following error is presented.
Traceback (most recent call last):
File “/galaxy-central/tools/graphlan/”, line 56, in
ctree.annotate( args[‘annot’], args[‘outtree’] if args[‘outtree’] else args[‘intree’] ) # ,

cl = list(self.tree.find_clades( {“name”: clade[:-1]} ))
File “/galaxy_venv/local/lib/python2.7/site-packages/Bio/Phylo/”, line 360, in match_attrs
found = elem.find_any(target, **kwargs)

sre_constants.error: nothing to repeat

Thank you in advance!
