Error convertng pw to YAMBO with p2y

Hello,
I am trying to reproduce the results of hBN. I ran YAMBO on quantum espresso files that are shared in the following link.
https://wiki.yambo-code.eu/wiki/index.p ... s_download
I downloaded hBN.tar.gz
I got the following error:

I saw similar posts on this but none of them seem to provide solution. How to fix the issue?
