Physical connection for both in-wall relay or switch requires both Line (so you can power it) wherever the in-wall relay or switch is (box). Load (to the light bulb) also comes from the same in-wall relay or switch. In addition to that you need Neutral and Traveler wires from secondary switch to primary switch (just as you showed in the second diagram).
While you have the correct number of wires as a total, you do not have them in the correct box.
Your second diagram has a dashed vertical line. Now draw the same line on the first diagram and compare them. you’ll see that you’re missing a wire between the boxes.
Another option would be to reroute Line to the same box where Load is.
