We were able to solve this problem by adding in the Object Assign polyfill to the files being imported and throwing the error  We would make it the highest import  that way it would be available to the other code to be called in the stack    import  mdn-polyfills Object assign    https   developer mozilla org en-US docs Web JavaScript Reference Global Objects Object assign Polyfill

After some days searching the Internet I found that this error usually occurs when an html element id has the same id as some variable in the javascript function  After changing the name of one of them my code was working fine

My problem was having type  application javascript  on the  lt script gt  tag for jQuery  IE8 does not like this  If your webpage is HTML5 you don t even need to declare the type  otherwise go with type  text javascript  instead

This is a common problem in web applications which employ JavaScript namespacing  When this is the case  the problem 99 9  of the time is IE s inability to bind methods within the current namespace to the  this  keyword    For example  if I have the JS namespace  StackOverflow  with the method  isAwesome   Normally  if you are within the  StackOverflow  namespace you can invoke the  isAwesome  method with the following syntax   this isAwesome      Chrome  Firefox and Opera will happily accept this syntax  IE on the other hand  will not  Thus  the safest bet when using JS namespacing is to always prefix with the actual namespace  A la   StackOverflow isAwesome
