I am getting a circuit breaker exception. I am trying to understand the error message.
I do not think I have ever seen Elasticsearch node run with successfully with a heap smaller than 512MB, especially for older versions like the one you are using, and that would generally only be suitable for a small test instance. I would recommend you increase the heap size to a minimum of 512MB.
