Request for Guidance on Updating CEF in Unreal WebBrowser Plugin

Hello [mention removed],

Thank you for your assistance — the steps you provided fully resolved the initial issue, and we’re now able to open the website in the built-in web browser as expected. Much appreciated!

However, we’ve encountered a new issue during the packaging phase. The cooking process completes successfully, but packaging fails with the following error:

`********** COOK COMMAND COMPLETED **********

********** STAGE COMMAND STARTED **********

Creating Staging Manifest…

Patching bootstrap executable; E:\projectname\Intermediate\Staging\project.exe

Can’t deploy D:\Resources\locales\af.pak because it doesn’t start with E:\projectname or D:\UE55C

(see D:\UE55C\Engine\Programs\AutomationTool\Saved\Logs\Log.txt for full exception trace)

AutomationTool executed for 0h 16m 23s

AutomationTool exiting with ExitCode=1 (Error_Unknown)

BUILD FAILED`Upon investigation, we noticed that af.pak and other localization files are located under:

D:\UE55C\Engine\Binaries\ThirdParty\CEF3\Win64\128.4.13+ge76af7e+chromium-128.0.6613.138\Resources\locales

However, the system appears to attempt referencing them from a different location:

D:\Resources\locales\af.pak

Could you please advise how we might resolve this deployment issue or adjust the path to keep everything within allowed directories?

Thanks again for your continued support!

Best regards,

Harut
