Hello Everyone,

I am working with modbus-RTU. It is working fine but after some time I am getting this error ( [error] [function:ad5d176.511d5e8] RangeError: Maximum call stack size exceeded).
Please help me out to resolve this error.

Here is my flow:

I dont think this part of your overall flows is your issue. I dont see any loops to cause a stack exceeded exception. You possibly have a loop somewhere else (e.g. subscribing to an MQTT topic that you later update ~ causing a feedback loop)

As for your flow - wow!

I would recommend you look into using the buffer-parser.

Thank you,
My issue is got resolved.
