Describe the bug you're encountering

Using parcel to build the script fails with:

node_modules/swagger-ui/dist/swagger-ui.js:8:32318: Cannot resolve dependency 'isArray'

To reproduce...

Build swagger-ui@3.21.0 using Parcel with the above "Swagger-UI configuration options".

Expected behavior

I expect it to build

Screenshots

Additional context or thoughts

I've fixed it on my personal setup by going into the package.json of swagger-ui and adding the dependency:
"isarray": "^2.0.4",

Start with package.json and the generated node_modules/swagger-ui/dist/swagger-ui.js referenced in the build error. Reproduce the npm-installed swagger-ui@3.21.0 build with Parcel, then verify that the package builds without the unresolved dependency error.
