I intend to loop the HTTP Request based on the number of Item Lists, there are 2 in my case.
Whilst the node variable preview showed the expected value, but on execution it showed as “undefined”. If I type it as fixed value it works, of course the other headers would failed until I typed it which isn’t what I want to do.
Your grant type is probably only available on the first item not the second. So you would need to make sure to always grab the first item’s value for that field. Or to add the value to the second item.
Hi @BramKn, the node variables are referring to an earlier node and has been working end to end but failed when I slot an item lists node in between for a valid reason. Since preview was showing the expected result, I don’t understand why the variable value not passing to HTTP Request.
Like I said, there is no value on the second Item.
There is a value on the first, so that goes fine. But when you split the items there is a second Item that doesn’t have a value.
When looking back a few nodes it uses the index of the item, which doesn’t exist in the node before it so it is undefined.
I already gave you 2 possible solutions, so please have a look at that.
Hi @BramKn , thanks for the explanation. I did a few test and confirm there isn’t any node variable value from the 2nd iteration onward. However I’m still struggling to get it work. Using the sample workflow below
can you show how to make reference to “always grab the first item’s value for that field”? The expected the result is
Brilliant! Thanks for spotting my mistake and patience in guiding towards the solution. It works great and I can continue to develop my work further. Thanks again!
