import {
  SeverityEnum
}
from'@typo3/backend/enum/severity.js';
import Modal from'@typo3/backend/modal.js';
class InfoWindow {
  static showItem(o, e) {
    Modal.advanced({
      type: Modal.types.iframe,
      size: Modal.sizes.large,
      content: top.TYPO3.settings.ShowItem.moduleUrl + '&table=' + encodeURIComponent(o) + '&uid=' + ('number' == typeof e ? e : encodeURIComponent(e)),
      severity: SeverityEnum.notice
    })
  }
}
top.TYPO3.InfoWindow ||
(top.TYPO3.InfoWindow = InfoWindow),
TYPO3.InfoWindow = InfoWindow;
export default InfoWindow;

Here top.TYPO3.settings.ShowItem.moduleUrl is accessed in line 23. However, ShowItem is undefined in new Window (perhaps in modal as well).

One solution would be to add the line

$pageRenderer->addInlineSetting('ShowItem', 'moduleUrl', (string)$this->uriBuilder->buildUriFromRoute('show_item'));

from https://github.com/TYPO3/typo3/blob/v13.1.1/typo3/sysext/backend/Classes/Controller/BackendController.php#L141 after https://github.com/TYPO3/typo3/blob/v13.1.1/typo3/sysext/backend/Classes/Controller/EditDocumentController.php#L802.

The other approach from my point of view would be to move top.TYPO3.settings.ShowItem into a condition and, if top.TYPO3.settings.ShowItem is undefined, check if window.opener.settings.ShowItem is available and then get the moduleUrl from it.

In discussion with Andreas Kienast, I would add a patch that sets the corresponding inline setting for Javascript is set in the EditDocumentController .

Perhaps this will also resolves #99467 and #99695.
