I was just having this issue with node-fetch today.

My error existed because I was trying to load from my npm prefix path ( ~ /.npm). In that path Mancy was try to load the node-fetch folder where it had directories of the installed versions, but it did not have the module itself.

Once I loaded the correct module path (~ /.npm/lib/node_modules) which had the actual node-fetch module, it loaded without a hitch, and I did not see another error about the missing prop id.
