app.doScript JAVASCRIPT stopped working

I have a script on every user account to call a script from a server, so every user has the same Version and doesnt need to install every updated script manually.

I assume an Update of InDesign or Mac, after years of flawless working it stops telling me:

"incompatible or not supported script language".

Script:

    var myScript = new File ("Marketing:Scripting:CI:ci work.jsx");
    if (myScript.exists)
         {
              app.doScript(myScript ,ScriptLanguage.JAVASCRIPT)
         }
