Trying to add to Ecency Vision

Trying to add to project results in an error. After adding the module via yarn, I am told I don't have loaders I need from only including a symbol from the library. Additionally I see these errors outputted on to the terminal:

I found this happens for only including a line with nostr-tools. Maybe it is a typescript issue?
