I have this code and when trying to make a Rest Client I get the error 

TypeError: Cannot read properties of undefined (reading 'replace')
    at C:\Users\**\Documents\shopify-app-sync\node_modules\@shopify\admin-api-client\dist\rest\client.js:86:30

I don't really understand what I'm doing wrong, it's probably obvious, but thanks for any help!
