How do I view a node in Drupal? I get errors if I set up a Next.js entity type

[skyeinthecloud]

I'm just wanting to view a node when I'm logged into my Drupal site as an admin.
If I set up entity types under /admin/config/services/next/entity-types

All I get is errors when visiting the node, e.g https://my-drupal-site.pantheonsite.io/blog/new-article

If Preview mode is configured for the entity type I get an Invalid URI exception, otherwise I get a getSitesForEntity() error.
Also do I even need to configure an entity type if I'm not using Preview mode...?

Config:

• Drupal 9.5.3
• Next-drupal 1.6
• PHP 8.1

@championlife What does your entity type config looks like?

[skyeinthecloud]

I'll post a few screencaps, thanks.

I think I have seen this when I had no url path Alias configured for a content type. Per https://next-drupal.org/learn/quick-start/configure-path-aliases

@twfahey1 Thanks! It didn't work initially when I created a Pattern and tried to Bulk Generate aliases.
But after manually editing a node -> clicking "Generate path alias" and re-saving it DOES work.

Because I had pre-existing nodes before I created a Pattern, it caused the error as Pathauto didn't Bulk Update those aliases.
Creating new nodes after I created the Pattern - it automatically generates an alias fine.

Are you able to get revalidate working without preview mode? It errors out for me when preview is not set, I believe its due to not knowing the site revalidate url?

AH01071: Got error 'PHP message: Uncaught PHP Exception Error: "Call to a member function getSitesForEntity() on null" at httpdocs/web/modules/contrib/next/src/Render/MainContent/HtmlRenderer.php line 115

I have the same question and concern as @TommyBloom: can we use the revalidation feature without enabling preview mode?
It seems that the current answer is 'no'. I needed to choose a Preview Mode plugin ("Site Selector") and check one of my Next.js sites in the entity type configuration to get revalidate working. Without selecting a site, revalidate will not work. I think the site selection setting should not be tied to the "Preview Mode" option. One should be able to select a site and then specify whether to use the preview feature, revalidate, or both.

Also, I had to set a "Preview URL" in the Next.js site configuration, in order to prevent the original error reported in this issue:
`InvalidArgumentException: The URI '' is invalid. You must use a valid URI scheme. in Drupal\Core\Url::fromUri() (line 293 of /app/web/core/lib/Drupal/Core/Url.php).

All of this forces the use of Preview Mode if you want to take advantage of on-demand revalidation.

One should be able to select a site and then specify whether to use the preview feature, revalidate, or both.

Agree on this. This makes sense.

The reason it works this way right now is revalidation was added in a later release. So we built it on top of the existing preview configuration for compatibility.

@camilo-escobar Would you be interested in creating a separate issue for this? I'm adding this to the roadmap for 2.0
