Hello,

I have been working on Canvas recently for a project however I can no longer use it as I get the 'Something went wrong' anytime I click on an element in my workbook. I have tried opening a new one and I have the same issue when I try to add any element. I have copied the error below. I haven't touched any of the files in the backend other than the usual configuration files.

```auto
Version: 6.5.3
Build: 18855
Error: Uncaught Error: Invalid arg type: textarea (https://[hostname]/bundles/vendors.bundle.js:208)
    at window.onerror (https://[hostname]/bundles/commons.bundle.js:3:858335)

```

Does anyone know how to solve this issue?

Thanks
