To Reproduce
- Clone the repo https://github.com/hdodov/test-nextjs/tree/cache-handler-not-working
npm inpm run dev- You'll see the error
Current vs. Expected behavior
I have "type": "module" in my package.json, so I can't add the cache handler like this, as the docs suggest:
module.exports = {
cacheHandler: require.resolve('./cache-handler.js'),
cacheMaxMemorySize: 0, // disable default in-memory caching
}Instead, I need to add it like this:
module.exports = {
- cacheHandler: require.resolve('./cache-handler.js'),
+ cacheHandler: import.meta.resolve('./cache-handler.js'),
cacheMaxMemorySize: 0, // disable default in-memory caching
}However, when I do so, I get the following error on npm run dev:
$ npm run dev
> test-nextjs@0.1.0 dev
> next dev

…and I also get it if I try npm run build directly:
