Common Error In my Dynamic Dash App

I have made a bunch of dash apps, and I’ve seen the same error in the Google Chrome console repeatedly:

Uncaught (in promise) TypeError: err.text is not a function at api.js:73

Just wondering if anyone else has also experienced this? It hasn’t affected any of my apps but I am wondering if it is because of something I am doing on my side that I should be doing differently or just a product of using a dynamic layout.
