NodeMCU Issues?

I tried this out with a NodeMCU by changing the LED pin to D4 and Button Pin to D3 (I changed it in the code as well). But when I upload my code, nothing happens; not in the Feed, the LED doesn't light up, but I stuck with the schematics just to stay safe. I tried to see if it was a problem with my NodeMCU, but it had no problem with any of the other sketches I had written. What can I do to correct this?

Don't change the code-- the suggested pin changes for NodeMCU are suggested because they work with the lesson code. The boards use different numbering conventions.
