Hi @--oooo--,

I had this exactly same error in our system when editing widgets, it was because there were too many or too few spaces in Client Controller code, see example below. After editing the code I was able to save my widget.

I got this error while trying to clone in the platform view, but was able to clone in the widget editor by using the options in the hamburger menu.

client controller must starts with api.controller at line no1 only. here in the screenshot we have space at line no1. remove the first line space and try it will work.
