Hi @praveenmak!
How did you manage to get this error?

  1. Is your Elasticsearch cluster in a green state?
  2. Did you install and configure our Elasticsearch plugin?
  3. if yes, what is the content of readonlyrest.yml?
  4. What is the file name of the two plugins you installed?

@sscarduzio,

it seems like my errors (other posts) where in fact if REST return a 404, or error, there is a problem to handle the response.

Thanks for responding, I fixed by using this.
