[BUG] setCPid() must be of the type int, null given

[fschoelzel]

Description

-- This Issue might be in the wrong Extension --

The settings array of the Slub/Dfgviewer/Controller/UriController is empty. So $doc->cPid is set to null instead of 0 if the storagePid is empty. (in this case the whole array is) Without the cast to (int) it throws an error.

• Option 1: we get back to $doc->cPid = max((int) $this->settings['storagePid'], 0);
• Option 2: we check for an existing settings array and storagePid key

Yes, for me it has fixed the problem. I can now display the document page. Have you cleaned cache? Maybe restart your ddev.
