Uncaught TypeError in admin when editing a page having Page Reference

[er314]

Short description of the issue

As non superuser, when editing a page having a Page Reference field (which has field-level access control), the rendering of the edit view fails, with :

Fatal Error: Uncaught TypeError: Illegal offset type in isset or empty in C:\xampp\data\www_smh\www\wire\core\Page.php:978 Stack trace: #0 C:\xampp\data\www_smh\www\site\assets\cache\FileCompiler\site\modules\AdminPageFieldEditLinks\AdminPageFieldEditLinks.module(155): Page->get(Object(PageField)) #1 C:\xampp\data\www_smh\www\wire\core\WireHooks.php(1050): AdminPageFieldEditLinks->{closure}(Object(HookEvent))

This is Page.php, line 978 :
if(isset(PageProperties::$basePropertiesAlternates[$key])) {

By catching the exception, it appears that $key is an object, of type ProcessWire\PageField,
actually it's a Page Reference field.

As a temporary measure, if I add the condition
&& !is_object($key)
then the rendering succeeds (but I have no idea of the implications, in terms of access control etc)

Note : Same pattern & issue on line 1397 :
if($value !== null && isset($this->wakeupNameQueue[$key])) {

Setup/Environment

• ProcessWire version: 3.0.203
• PHP version: 8.0.15

Hi, that error is caused by the module AdminPageFieldEditLinks and was fixed in this commit. Please download the current version of the module from AdminPageFieldEditLinks/releases . Unfortunately the version numbe was not incremented, that’s why ProcessWire does not find the new version in the module section.

Ah yes, sorry, I forgot that AdminPageFieldEditLinks was a third-party module.
Thanks a lot for directly pointing to the root cause ; I confirm that the module update fixes the error.
