Cannot read property '0' of undefined

Dear nodered Experts,

I have this simple function that gets the value of msg.payload and loop through that value to get specific data, how ever I am having an error of "Cannot read property '0' of undefined.

I don't know how this happen. Anyone has already encountered this?
This is my function:
funct

And this is the output of the debug node:
debug

The second message is actually my data on which I like to loop on.

Thank you. I hope you can help me in here.

With kind regards,
Henjoe

tag is just the iterator - so you probably want
payload: tags[tag].value[0]
