Hello,

This occurs when one of you on change client script is unable to read any field on the form. Check which onchnage client script is causing the issue, then in the script of you have any field which the script is not bale to read maybe because the field is not available on the form.

You can read a support article for a similar issue:-

Hello,

There should be one client script defined onchange of Product type field. Validate if the script has any errors, potentially there should be undefined variable name or you might not be getting value from in the variable from which you are reading values.

It would be helpful if you can post the client script here for validation.

Thank you,

Ali

The onchange event occurs when the value of an element has been changed. For radiobuttons and checkboxes, the onchange event occurs when the checked state has been changed.
