ReferenceError: Kg is not defined

I am using Next.JS for my project. All of a sudden I am getting this error. "ReferenceError: Kg is not defined", after debugging it i found the file which is causing this issue. file name is VM3284, file content is

(function Rn(SJ, Vf) {
    //somecode
  let GB = UL ? UL ? "tCtx" : po : po
      , IF = UL ? Kg + GB : wX
      , IQ = UL ? 4 : VW
      , C = nK ? 0 : po;
  //somecode
}

I don't know if is this a third-party library code or something.

I tried googling it but didn't find the answer. please help me out.

Solution

  • I had the same error "KG is not defined" it started after adding a free video with url. Finally I found out that the error made by an add-Block chrome extension. After i deleted the extension the error stopped.
