FBXLoader Jest testing error

I keep getting this error when testing with jest. It’s pretty verbose but I’m still unable to figure out what’s wrong. It’s with my FBXLoader import:

 Test suite failed to run

    Jest encountered an unexpected token

    This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

    By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

    Here's what you can do:
     • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/en/ecmascript-modules for how to enable it.
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/en/configuration.html

    Details:

Should I maybe import the FBXLoader differently?

Have you been able to resolve this issue?

Please don’t get excited when you see my reply as I honestly can’t remember :sweat_smile: I think what this error was, was the version of Jest or Stencil (they were not compatible at the time) and I think what I did was roll back to the previous version of Jest and the error went away. I think
