Elasticsearch-migration plugin not working on es 2.4.0/ 2.4.1

Hi,

I am trying to run the elasticsearch migration plugin on es-2.4.0 and es-2.4.1 clusters. I do not get any output from the plugin. I do not see any errors on the webpage or in the elastic logs. How can I figure out why it is not working ?

PS:

I do have cors enabled and the http.cors.allow-origin set to "*"

If it helps, I am getting the following error in the webpage

Uncaught SyntaxError: Duplicate data property in object literal not allowed in strict mode : main.js:1546

there is a updated version of migration plugin now that supports es2.4
