@JLowe3 are you using nuxt.js by chance? If so, it might be trying to run the script server side instead of client side. Try putting it inside a client only component as described here: https://nuxtjs.ir/api/components-client-only
We’re just using standard Vue 3. However, I seem to have fixed the issue, we’re using Azure App Insights in our application and we have a setting enabled that allows us to trace every HTTP request in the app for debugging.
This adds a “traceparent” header to each request and hubspot doesn’t seem to allow that so we’ve allowlisted the hubspot domain in the App Insights config and everything is working perfectly.
