It seems that using the optional catch all route next js picks every request, meaning also assets requests

[Error: An error occurred in the Server Components render. The specific message is omitted in production builds to avoid leaking sensitive details. A digest property is included on this error instance which may provide additional details about the nature of the error.] {

{
  params: { slug: [ 'manifest', 'site.webmanifest' ] },
  searchParams: {}
}
Error: Error: Cannot read properties of undefined (reading 'template'), Slug: site.webmanifest

This is a log example; as you can see, the props.params contains manifest and site.webmanifest which are just files...

Any clues here? I'm using the latest version of next js
