Hello @tanz ,
if your JSON is not stored in an array no need to access it like [0] for accessing first element
replace like below
Just make sure before send the JSON as a event parm1 use JSON.stringify(your_json)
And then access it like below
var parsedData =event.parm1;
var txId =MessageBody.u_tx_id;
var state = parsedData.MessageBody.state;
Hope this helps
Mark the answer correct if this helps you
Thanks
