Root cause
Function: index.php?p=admin/actions/asset-indexes/process-indexing-session&v=1680710595770 After loading completed, progess will load: "skippedEntries" and "missingEntries" These parameters is not yet filtered, I just tried "skippedEntries" but I think it will be work with "missingEntries"
My reponse:
{ "session": { "id": 10, "indexedVolumes": { "6": "\"" }, "totalEntries": 2235, "processedEntries": 2235, "cacheRemoteImages": true, "listEmptyFolders": false, "isCli": false, "actionRequired": true, "dateCreated": "Apr 5, 2023, 9:03:16 AM", "skippedEntries": [ "\"/assetpreviews/Image.php", "\"/assetpreviews/Pdf.php" ], "missingEntries": { "folders": [], "files": [] }, "processIfRootEmpty": false }, "skipDialog": false }
