Not working with Vue 2 and Webpack 5

Describe the bug

Thanks for the nice package to use Chart.js 3 with Vue 3! I would like to use this to simplify my migration from Vue 2 to 3.

but when using vue-chart-3@legacy with webpack, I get the following error.

ERROR in ./node_modules/vue-chart-3/dist/index.mjs 33:0-44
Module not found: Error: Can't resolve 'lodash-es/startCase' in '/Users/shingo.sasaki/webpack-vue-2-vue-chart-3/node_modules/vue-chart-3/dist'
Did you mean 'startCase.js'?
BREAKING CHANGE: The request 'lodash-es/startCase' failed to resolve only because it was resolved as fully specified
(probably because the origin is strict EcmaScript Module, e. g. a module with javascript mimetype, a '*.mjs' file, or a '*.js' file where the package.json contains '"type": "module"').
The extension in the request is mandatory for it to be fully specified.
Add the extension to the request.

My solution

It seems that esm is supported for vite, but the standard webpack configuration does not solve this problem.

The following settings may resolve, but I would be grateful if you could specify the extension in components.ts. https://webpack.js.org/configuration/module/#resolvefullyspecified
