I created a String field with just de follow code:

if (true) {
    return 'R$ XX,xx' + doc['AdditionalData.ResponseMessage.AmountAuthorized'].value;
}

It don't works. When i put if statement crashes with the follow exception:

Error: Request to Elasticsearch failed: {"error":{"root_cause":[{"type":"script_exception","reason":"compile error","script_stack":["if (true) { return 'R$ XX ...","^---- HERE"],"script":"if (true) { return 'R$ XX,xx' + doc['AdditionalData.ResponseMessage.AmountAuthorized'].value; }","lang":"painless"}],"type":"search_phase_execution_exception","reason":"all shards failed","phase":"query","grouped":true,"failed_shards":[{"shard":0,"index":"buy4-authorizationprovider-2017.05.12","node":"8lWOf-9KROa5e_csz1ufPw","reason":{"type":"script_exception","reason":"compile error","caused_by":{"type":"illegal_argument_exception","reason":"Extraneous if statement."},"script_stack":["if (true) { return 'R$ XX ...","^---- HERE"],"script":"if (true) { return 'R$ XX,xx' + doc['AdditionalData.ResponseMessage.AmountAuthorized'].value; }","lang":"painless"}}],"caused_by":{"type":"script_exception","reason":"compile error","caused_by":{"type":"illegal_argument_exception","reason":"Extraneous if statement."},"script_stack":["if (true) { return 'R$ XX ...","^---- HERE"],"script":"if (true) { return 'R$ XX,xx' + doc['AdditionalData.ResponseMessage.AmountAuthorized'].value; }","lang":"painless"}},"status":500}
