OnComplete called before archiving is completed and crashing #8

ZipBlueprint I am trying to zip all files of a directory. I tried using both AddEntriesFromStorageand AddEntriesFromStorageDirectory. It seems that the OnCompleteevent is called immediately, before the archiving is complete, because some times if I wait after the OnCompleteevent, the zip is created correctly. Also if I add the CloseArchivenode after ![ZipBlueprint](https://github.com/user-attachments/assets/f206fd96-3eef-42df-93c1-5b16103a03c6)it causes an error (even when the zip is extracted correctly): Error: Blueprint Runtime Error: "Accessed None trying to read property CallFunc_CreateRuntimeArchiver_ReturnValue". Node: Close Archive Graph: EventGraph Function: Execute Ubergraph W Main Menu Blueprint: W_MainMenu

Sometimes, if the file is larger (example 100Mb) the engine crashes even before I close the application, to this line (miniz.c , line 5938): if ((int)pState->m_pZip->m_pWrite(pState->m_pZip->m_pIO_opaque, pState->m_cur_archive_file_ofs, pBuf, len) != len)

with the error:

Unhandled exception at 0x000002A60A28594C (UnrealEditor-RuntimeArchiver-Win64-Debug.dll) in UnrealEditor-Win64-Debug.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.

The first thing that catches my attention is that you're not setting the archiver instance as a strong reference, which means the garbage collector will collect it prematurely. You could, for example, assign it to a separate variable in Blueprints right after its creation, as shown in the Blueprint examples, and then try again
