Hi guys,

When searching through paragraphs the queue breaks because of the following error

An AJAX HTTP error occurred.
HTTP Result Code: 200
Debugging information follows.
Path: /global/batch?id=239131&op=do_nojs&op=do
StatusText: OK
ResponseText: Error: Call to a member function getEntityTypeId() on null in Drupal\scanner\Plugin\Scanner\Paragraph->search() (line 56 of /var/www/html/web/web/modules/contrib/scanner/src/Plugin/Scanner/Paragraph.php).

Will try to investigate and find the cause of this issue.

We'll need to include test coverage for this.

There's another issue for this that has a patch/merge request, so let's close this one and work on the other one.

This issue is still reproducible. As Stephen mentioned in #3196225, I updated the module to 2.0.x version, using Drupal 10.6.2. Here is what the error trace looks like:

I believe we need to add null or empty checks to avoid errors when processing Scanner results. The main issues are:

1. Match count increments in ScannerForm fail when $data['field'] is empty
2. Regex processing in the Node scanner does not validate $matches[0] before accessing it
3. Paragraph scanner does not safely handle orphaned paragraphs or nested entity hierarchies

Attached is the MVP patch that ensures null checks are added before processing field data, regex matches, and handling orphaned paragraphs, and that safely traverses nested entity parents. This issue now needs tests.
