Migrating to Bridge throws unhandled error

[chrpeters]

I am currently migrating an application from Nuxt 2 to Bridge.
When running nuxi preview, I am seeing constant error messages coming in, but I am unable to pinpoint the origin.
Would anybody have a clue where to start looking? The application seems to be running without any errors in the browser console.
Thank you.

I had the same problem and had no idea what the problem was. Everything was OK on the page, but the console kept printing that error.
