I have a CRA project that's being deployed using Heroku. Deploying to production has never been an issue, but now when I try I get the following error:

-----> Installing dependencies

All the versions of serialize-javascript that are installed:

% npm ls serialize-javascript   
on-borrowed-time@0.1.0 /Users/mpetersen/Documents/dev/on-borrowed-time
├─┬ eslint-loader@4.0.2
│ └─┬ webpack@4.44.2
│   └─┬ terser-webpack-plugin@1.4.5
│     └── serialize-javascript@4.0.0
└─┬ react-scripts@4.0.1
  ├─┬ terser-webpack-plugin@4.2.3
  │ └── serialize-javascript@5.0.1
  └─┬ workbox-webpack-plugin@5.1.4
    └─┬ workbox-build@5.1.4
      └─┬ rollup-plugin-terser@5.3.1
        └── serialize-javascript@4.0.0

Does anyone know why 'serialize-javascript@5.0.1' is not in the npm registry? I've tried updating react-scripts but it causes other dependency issues in my project.
