Hi All,

I have ran into a problem while upgrading my Elasticsearch license. Please see the Error below. I am quite new to ES. Need some help please?

{"error":{"root\_cause":[{"type":"illegal\_argument\_exception","reason":"failed to parse license source"}],"type":"illegal\_argument\_exception","reason":"failed to parse license source","caused\_by":{"type":"json\_parse\_exception","reason":"Unexpected character ('\<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@1baf9d0d; line: 1, column: 2]"}},"status":400

Thanks,  
Vivek
