RangeError issue with buffer-parser node (Attempt to access memory outside buffer bounds)

[Darren]

Screenshot:

node-red-contrib-buffer-parser is erroring with RangeError: Attempt to access memory outside buffer bounds, but is only receiving an empty array at the moment due to sensors being shut-down. It appears to be causing a noticeable slowdown with node-red deployment and loading (peak CPU load is around 5% on the RPi), and I'm not sure how to better handle this error.

Can anyone advise on possible solutions?

Many thanks,

Use a switch node to check the payload BEFORE it goes into the buffer parser. If the msg.payload.length is 0, don't let the message pass.

Thank you so much! That has solved the issue with buffer-parser!

My connection to node-red is still sluggish, but I suspect that may be our clients' internet connection, or I need to implement stricter rate limits elsewhere in the code.
