Error: Call to undefined method Drupal\node\Entity\Node::getBook()

I am getting this error on all pages site wide. This occurred on update to ^3.0.2

Error: Call to undefined method Drupal\node\Entity\Node::getBook() in Drupal\book\Plugin\Block\BookNavigationBlock->build() (line 176 of modules/contrib/book/src/Plugin/Block/BookNavigationBlock.php).

Please confirm if the latest release fixed the issue. 3.0.2 had a big change that was needed

The update from 3.0.0 to 3.0.2 is what introduced the issue on my system.

Seems to be a very similar issue. These are content types that have no Book configuration at all. They are not parents or children content types. There is a Book Navigation Block displayed on the page layout that displays all available Book(s) Top Level. Here is the stack trace.
The website encountered an unexpected error. Try again later.

Thanks but did you try the MR mentioned? Did you upgrade to 3.0.3?

I have updated to 3.0.3 and this issue is persistent. If I remove the Book Navigation Block from the layout all pages render flawlessly. When the Book Navigation Block is present, pages that are not of a Book content type will not render.

Not sure this is proper but wrapping in a Try/Catch allows render. At line 222

$node = $this->routeMatch->getParameter('node');
if ($node instanceof NodeInterface) {
try {
$book = $node->getBook();
if (!empty($book['bid'])) {
$current_bid = $book['bid'];
}
} catch (\Throwable $th) {
//throw $th;
}
}

Need clearer steps as I'm not able to replicate any error.

Try this

I suggest trying the fix in the related issue, #3586802: Book block visibility condition fatals on non-book node routes by calling getBook() on core Node.

I think the issue here is that book is not allowing the block navigation to display on non-book node pages and some of us want the book block navigation to display on all pages in a layout regardless of whether the current node is part of a book. My site uses book heavily including several different books as documentation and want to provide a navigation tree to those books using the existing book navigation without having to create a new menu.
