While importing through Backend Import Module I'm getting an Exception: Authentication Context Confirmation Required

[zwenn]

After upgrading from Typo3v12 to Typo3v13 and external_import from version 7.3.0 to 8.2.0 with svconnector 7.0.0 and svconnector_csv 6.0.0

The following Exception is thrown while importing through Backend Import Module of external_import or scheduler task:
An exception occurred while saving the data: Authentication Context Confirmation Required (code: 1743597646, location: /.../vendor/typo3/cms-backend/Classes/Hooks/DataHandlerAuthenticationContext.php at line 106)

Also after removing all of my custom steps this exception is thrown.

Because I want to import be_users, my Configuration is inside of Configuration/TCA/Ovverrides/be_users.php

I found this: https://forge.typo3.org/issues/107752?tab=history but no solution.

Maybe you have some advice for me.

Hi. You have to stick to svconnector 6 and svconnector_csv 5. Although the versions you mention are all compatible with TYPO3 13, external_import is not yet compatible with svconnector 7.

I'll keep that issue open. You're not the first one to stumble upon this and I might do a minor release of external_import restricting the compat range with svconnector.

Sorry for the confusion.

Hi. Thank you for the fast answer. But the exception is still thrown.

I found this:

• https://typo3.org/security/advisory/typo3-core-sa-2025-013
• https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ApiOverview/Events/Events/Backend/SudoModeRequiredEvent.html

After integrating the SudoModeRequiredEvent Listener the import of the be_users work.

But in my custom step I also would like to use the DataHandler but at that point the exception is thrown again.

Ah, interesting! I hadn't thought about that. And the event is not fired when you use the DataHandler in your custom step? Can't you disable the sudo mode verification at that point too?
