Site scan fail with custom post type

[fellyph]

Bug Description

When the user selects only a custom post type to be served by AMP, at the plugin's settings the site scan fails. To reproduce this behavior, I have created a simple custom post type and selected only this CPT to be served by AMP. The result is, the site scan started to fail because wasn't able to find AMP URLs.

Expected Behaviour

If the user selects a specific custom post type, the site scan should be able to point to the new URLs

Did you create a Movie post in addition to having registered the post type?

Hi @westonruter,

No, I haven't it was empty when I checked.
When I've included one Movie post it is working fine.

OK, then that's probably a pretty rare scenario, right?

If anything, when no scannable URLs are returned perhaps a special notice should be displayed saying that no URLs are available. This would be better and more specific than "Site scan failed. Try again."

Sure, this is a rare scenario.

The message is not clear, that is why I got confused.

For example, if no post type is selected a different message is displayed:
