Craft 5: Getting a lot of null variable errors

[LinneaHarts]

Trying to use this on craft 5 (Craft 5.6.4, MariaDB, PHP 8.2), whenever I drill down to the field usage, I'm getting a null variable error.

e.g.

Twig Runtime Error – Twig\Error\RuntimeError
Impossible to access an attribute ("name") on a null variable.

   {% for entry in blockEntries.entries %}

                          <tr>
                              <td>{{ entry.id }}</td>
                              <td>
                                  <a href="{{ entry.cpEditUrl() }}">{{ entry.title }}</a>
                              </td>
                              <td>
                                {{ entry.section.name }}
                              </td>
                              <td>
                                {{ entry.type.name }}
                              </td>
                          </tr>
   
                      {% endfor %}
                  </tbody>
              </table>
   

OR

Error
Call to a member function getOwner() on null

Same here

@chrisrowe unfortunately this bug makes this awesome plugin unusable for us right now. I can send you our database so you can reproduce the issue on your end if you want me to. :)

@samuelreichor Sorry about that, this one has taken a back burner recently. Let me take another look this week!

@chrisrowe I just looked into it, and the “getOwnerId” error occurs when an entry type has been deleted in matrix fields.

$topLevelEntries = $entries->map(function($entry){
                    $owner = $entry->getOwner();

					// change start
                    if ($owner === null) {
                        return $entry;
                    }
					// change end

                    try {
                        $owner = $entry->getOwner();
                        while($owner->getOwner()) {
                            $owner = $owner->getOwner();
                        }

                        return $owner;
                    } catch(Exception $e) {
                        return $entry;
                    }
                })->unique();

maybe this helps :)

Just added a quick pr for this: #15
