TYPO3 Core

Hi, sorry for my late reply. I can confirm a related issue to the one from David Rellstab. But for me it is however not possible to use any selection or staging action. Page and language selection are both empty and thus grayed out.

Calling

/typo3/index.php?route=%2Fajax%2Fworkspace%2Fdispatch&token=xxx

Uncaught (in promise) s.AjaxResponse {response: Response}

TypeError: Cannot read property 'requestContent' of undefined

Found an additional entry in the backend log:

Core: Exception handler (WEB): Uncaught TYPO3 Exception: Undefined class constant 'SIGNAL_GenerateDataArray_BeforeCaching' | Error thrown in file PATH/typo3/sysext/workspaces/Classes/Compatibility/SlotReplacement.php in line 50. Requested URL: DOMAIN/typo3/index.php?route=%%2Fajax%%2Fworkspace%%2Fdispatch&token=--AnonymizedToken--

I hope this can help out to narrow it down.

Hi David, this should be fixed with https://review.typo3.org/c/Packages/TYPO3.CMS/+/68793. Can you please check?

Hi Marco,

thanks for sharing more details. This looks like the XHR request fails due to some error in the corresponding PHP code.

Do you use any workspace related Hook / SignalSlot / Event which may trigger this error?

Found an additional entry in the backend log:

This is really curious, since the constant is definitely defined in v10: https://github.com/TYPO3/TYPO3.CMS/blob/v10.4.15/typo3/sysext/workspaces/Classes/Service/GridDataService.php#L48
