Deploying a Gatsby Site Hangs Forever

I created a static site using Gatsby and am attempting to deploy it on Netlify. Per the Gatsby instructions for Netlify, I ran gatsby build which worked fine and then drag and dropped the folder on Netlify. It’s been hanging for 30+ minutes with no messages logged. What can I do to get the build to actually happen?

Here’s a pic of what I see on Netlify:

Hi @strangeforloop, it looks like you are doing a manual deploy. I recommend reading the suggestions here: [Support Guide] My drag and drop deploy is stuck in "Uploading" status
