I'm trying to make it so in my Vapi workflow I can play an audio clip. I tried setting up a Vercel api but it keeps giving me a network error when I test the tool. Any thoughts?

Make sure vapi.start() is triggered by user click to avoid browser autoplay blocks, serve your audio file from Vercel’s /public folder not via fs, and if using a Vercel API route, increase the function’s timeout in vercel.json to avoid network errors during streaming..
