Can't Launch Session in UEFN since v41.10

Summary

Hi everyone,

when trying to launch a session in UEFN, validation fails and I’m getting the following output log error:

LogOnlineSchema: Error: Invalid schema category Lobby: Service descriptor id Lobby not found.
LogOnlineSchema: Error: Invalid schema category LobbyMember: Service descriptor id LobbyMember not found.

LogValkyrieSyncProject: Error: Failed to Query project depenency API: Failure ErrorCode=errors.com.epicgames.content-service.module_not_found, Message=Could not find the requested resource, Raw={

“errorCode”: “errors.com.epicgames.content-service.module_not_found”,
“errorMessage”: “Could not find the requested resource”
}
LogValkyrie: Error: FlowStep_RunLocalValidation(): Failed request to validate project source data: Validation failed

I’ve created and own the project, so I can’t really understand the verification part.
For the api part: As far as I understand, it is on Epic’s end, since the host content-service is mentioned. as […]epicgames.com.

I also checked my files if there is anything related to “63319361-4f00-113b-4f86-51ac6a5297df”, none found.

Thanks for your help in advance!

hi @ui_visuals

Try the validation fix. If this fails try fixing each error one by one with Fix Up

hi @Jimbohalo10

thank you very much. yes I can log into my UEFN content store. and fixing errors one by one helped!

some of my wbp and umg work got deleted, but it’s a sacrifice I can live with.

hi @ui_visuals ,

Glad it helped. My recommendation is to WinRAR/zip up you project now so if something else gets deleted . All my published Islands are stored this way on a USB in case my PC crashes or corrupts. Fix Up is a very good tool if you fix one by one.

URC is good but you cannot beat a WinRAR backup,

Each Major milestone like getting past the First FN Private version and publishing is worth a backup
