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`
