Im also receiving the same error when attempting to setup a new watch.  
{  
"error": {  
"root\_cause": [  
{  
"type": "script\_exception",  
"reason": "failed to compile script [ScriptException[scripts of type [inline], operation [elasticsearch-watcher\_watch] and lang [groovy] are disabled]] with lang [if (ctx.payload.aggregations.minutes.buckets.size() == 0) return false; def latest = ctx.payload.aggregations.minutes.buckets[-1]; def node = latest.nodes.buckets[0]; return node && node.memory && node.memory.value \>= 75;] of type [groovy]"  
}  
],  
"type": "script\_exception",  
"reason": "failed to compile script [ScriptException[scripts of type [inline], operation [elasticsearch-watcher\_watch] and lang [groovy] are disabled]] with lang [if (ctx.payload.aggregations.minutes.buckets.size() == 0) return false; def latest = ctx.payload.aggregations.minutes.buckets[-1]; def node = latest.nodes.buckets[0]; return node && node.memory && node.memory.value \>= 75;] of type [groovy]"
