Pattern-visitor.js - Uncaught TypeError

Posted 6 months ago by stefan7

Hi, I have no idea where this error is coming from:

Uncaught TypeError: Cannot read property 'toString' of undefined
    at Object.<anonymous> (pattern-visitor.js:32)
    at Object.<anonymous> (pattern-visitor.js:32)
    at __webpack_require__ (pattern-visitor.js:26)

Any suggestions where to look or how to solve?

Thanks Stefan
