When working in the New Model Section the user clicks Expose Hidden Fields and the following error is generated:
"readonly is not a valid value for Boolean"
Release : 17.3
Browser cache seems to have caused this error
We were originally testing in Google Chrome and experienced the error.
We then tried in Firefox and did not encounter the error.
After updating Chrome to the latest version (114.0.5735.134 at the time of this KB) and then clearing the cache, we were able to expose the hidden fields successfully.
