Uncaught Syntax Error when using Gatsby Start Blog + IPFS

So I'm trying to deploy the Gatsby Starter Blog to IPFS. I follow the instructions to set up gatsby-plugin-ipfs, and I get the following error in my console after viewing the website on localhost:

Uncaught (in promise) SyntaxError: Unexpected token _ in JSON at position 1132
    at JSON.parse (<anonymous>)
    at Object.YZX3 (commons-56a4a8d1b87de487b0b8.js:1)
    at u (bootstrap:102)
    at Object.6Gk8 (bio.js:15)
    at u (bootstrap:102)
    at Module.RXBc (index.js:1)
    at u (bootstrap:102)

I've made zero changes to the starter so I'm wondering what's going on. The starter by itself without the plugin does not have this issue.
