It seems to have a problem finding '@medusajs/types'
Indeed if I look at files referring to that, they are red underlined.

run dev works fine.

pnpm run build

medusa-next@1.0.3 build
next build

next.config.js {
"experimental": {
"serverComponentsExternalPackages": [
"@medusajs/product",
"@medusajs/modules-sdk"
]
},
"reactStrictMode": true,
"images": {
"remotePatterns": [
{
"protocol": "http",
"hostname": "localhost"
}
]
},
"env": {}
}
