core.js:647 Handler of component is invalid -> TypeError: Cannot read property 'flow' of undefined

Recently we see these errors coming up over and over again in Author when designer templates, forms, ...

 

Any clue where this is coming from. core.js is not a script file we can read easily.

@rakhi_sukhadeve 

The issue is noticed in the browser when doing development. 

 

We normally use Chrome for development (Version 83.0.4103.97 (Official Build) (64-bit), this morning I tried Firefox and the issue does not occur in Firefox. 

I happen when you want to edit a template or adaptive form or site, just anything once you go into edit mode it will appear. Sometimes 1 error, sometimes 3, occasionally the error appears 5 times at one go.
