I've tried to reproduce the issue locally, on multiple machines, but I always get a pass.
Please confirm that you tried installing this from CPAN yourself and what method you used.
I tried installing it, and I noticed some warnings:
WARNING: the following files are missing in your kit:
Please inform the author.
When I click on a link from the MANIFEST for
MYMETA.json, I get this error:
The requested URL /src/ADAMDH/WWW-Shopify-0.11/MYMETA.json was not fou
+nd on this server.
I'm not saying that is the root of your problem, but that does seem strange.
