fix(next): skip custom views without path prop in getCustomViewByRoute

[jakenorthey]

When using the @payloadcms/plugin-otp plugin, when the plugin redirects to the OTP screen, it reads the admin custom views config. If any views exist without the path property defined, the call to getCustomViewByRoute will fail with the error below:

TypeError: Cannot read properties of undefined (reading 'length')
    at <anonymous> (getCustomViewByRoute.ts:32:28)
    at getCustomViewByRoute (getCustomViewByRoute.ts:31:29)
    at getRouteData (getRouteData.ts:347:20)
    at RootPage (index.tsx:75:7)

This fix skips any custom views that do not have path defined.

This fix skips any custom views that do not have path defined.

This doesn't seem right. The path property should be required on all non-default root views. If you set up a custom view, it is expected that you'd provide a path for that view to mount to.

This feels more like a types issue than anything. The reason it's not required across the board is probably because we allow partial overrides of default views, like dashboard, etc. which provide their own path. To me it feels like we should require path on all non-default views.

If you're building a custom dashboard view, for example, you should be able to swap out only a portion of the config (omit the path):

{
  // ...
  admin: {
    // ...
    components: {
      // ...
      views: {
        dashboard: {
          Component: '/MyCustomDashboard'
        }
      }
    }
  }
}
