WhatsApp Media Node – “No execution data available” error (from YouTube tutorial)

Hey! I was following this YouTube video step-by-step:
:tv: https://www.youtube.com/watch?v=UXn4y0aOzOs
In the part where we drag the media.id into the “Get Audio File” node (media param), I get this error:
No execution data available
Tried dragging the field directly and also mapping via Set node, but still doesn’t work.
Static media ID works fine though.
Anyone else faced this or knows how to fix it?
Thanks!

In some circumstances, to use drag & drop for filling in expressions, the previous node(s) in the workflow need to be test-executed first. Try clicking the “play” button on the node just before the one you are editing (orange triangle in screenshot below), and then try your drag & drop again.
