I can't seem to find any documentation on how to format a module field in the argument mapping for a custom function in my Instant Action. I would like to send the lead id to the function. I have tried every possible version that I think of, and there don't seem to be any topics on this. My function accepts a string of the lead ID and works perfectly well in testing, and it's running without error, but it's not updating what I need to update because it isn't receiving a valid value (I guess.. I haven't figured out anyway to log what in the heck it is receiving).  The attachment includes one of the 500 ways I have tried to format the field name.
