With your SDK I get:
success={“0”:"{",“1”:""",“2”:“m”,“3”:“e”,“4”:“s”,“5”:“s”,“6”:“a”,“7”:“g”,“8”:“e”,“9”:""",“10”:":",“11”:""",“12”:“I”,“13”:“n”,“14”:“v”,“15”:“a”,“16”:“l”,“17”:“i”,“18”:“d”,“19”:" “,“20”:“w”,“21”:“h”,“22”:“e”,“23”:“r”,“24”:“e”,“25”:” “,“26”:“c”,“27”:“l”,“28”:“a”,“29”:“u”,“30”:“s”,“31”:“e”,“32”:”.",“33”:" “,“34”:“N”,“35”:“o”,“36”:“t”,“37”:” “,“38”:“E”,“39”:“x”,“40”:“i”,“41”:“s”,“42”:“t”,“43”:“i”,“44”:“n”,“45”:“g”,“46”:” “,“47”:“c”,“48”:“o”,“49”:“l”,“50”:“u”,“51”:“m”,“52”:“n”,“53”:“s”,“54”:”:",“55”:" “,“56”:“x”,“57”:“x”,“58”:“x”,“59”:”"",“60”:",",“61”:""",“62”:“c”,“63”:“o”,“64”:“d”,“65”:“e”,“66”:""",“67”:":",“68”:“1”,“69”:“0”,“70”:“1”,“71”:“7”,“72”:"}",“type”:"",“name”:""}
With the one I sent you, I get:
success={“type”:"",“name”:"",“message”:“Invalid where clause. Not Existing columns: xxx”,“code”:1017}
In both cases, the success callback fires.
Note: I am working in nodejs, that’s why the weird result above. This is apparently an issue with your standard SDK and nodejs that you are aware of and will fix in the next release.
