Native Customer Search Stops Working

After adding some fields to the Order Entry app, I’ve noticed the native Customer field and search icon have stopped working. When clicking on the search icon, I get the console error below. When manually entering a Customer ID, the app does not retrieve any information for the customer. I’ve not touched the Customer field.

Any insight is appreciated so I don’t have to restart from the Base app.

Error:
