Hello everyone, I am running into a problem when I import a flow I had built on the IBM Cloud Node Red to my local Windows 10 Node Red. The flow is as follows: [image] When I run this on the IBM cloud, it works perfectly. When I run it locally on Windows 10, I get the following debug outputs: [i…

I seem to remember others have had problems with this node, my suggestion would be to replace it with a normal Function node using javascript.

Thank you for the suggestion! The problem is that I am not familiar with the JS syntax so when I tried to replace Python with it, I couldn't get all the functions in my flow to do what I want :broken_heart: I was able to convert the function in the question to the following: //variables to be used…

Oh, I haven't tried these nodes before, thank you for the suggestion! I'll read more about them and see if I can figure them out

I don't know what the problem is with the 'too many errors' message, it seems to be a bug in the syntax checker used in the function node, but not certain. @dceejay will have to comment on that I think. For the second issue with the function just not doing what it should then an easy way to do sim…

[image] Colin: For the second issue with the function just not doing what it should then an easy way to do simple debugging is to use node.warn() to show the progress through. So for instance you could add at appropriate points lines like node.warn("morseLetter is " + morseLetter) Thank you …

It seems to be triggered by all the else if lines. That code would be better written using the javascript switch statement so it might be worth changing over to that anyway. https://www.w3schools.com/js/js_switch.asp

Ok, so I tried switch now and the yellow error moved to an earlier place in the message (at letter q) and now says 70% scanned instead of 97% but it is still showing. However, now that I have a version with if and one with switch and need to decide which one to keep; why do you think Switch is bett…

Isn't the switch version easier to follow? I don't know whether the switch generates more efficient code, it may well do. It is more about using the appropriate construct for the requirement. Where you want to test a variable for equality to a number of different possibilities then that is what s…

I thought I might have found the cause of the warning triangle. In javascript it is not recommended to use for .. in .. for iterating an array, though in practice it may work. The recommended way is to replace, for example for (var letter in msg.payload) with for (var letter=0; letter<msg.paylo…
