The following error is thrown when trying to use a vanilla installation of next.js with the swr library and preact:

To repro using Preact:

git clone git@github.com:kevlened/nextjs-preact-swr-repro.git
cd nextjs-preact-swr-repro
yarn
yarn dev

To see the expected behavior when using normal React:

git clone git@github.com:kevlened/nextjs-preact-swr-repro.git
cd nextjs-preact-swr-repro
git checkout react
yarn
yarn dev
