log
is not a built-in function.
As it looks like you are trying to do a logarithm, then you want to use Math.log()

Hi ,
When I do that the console says “function tried to send a message of type number “
That is because you are returning just a Number and not a valid message object.
Instead of return temp
, you should do:
msg.payload = temp;
return msg;
