Crash if opening DataTable with Key inside struct


Found a bit weird bug while was making my system for marketplace.

If you crate a struct with key type of info, and then use this struct for DataTable, then editor will crash on Asset opening atempt.

Here is a video: - YouTube

The funny thing is if keys are under array type, everything works fine.

Hi AIFlakky,

Unfortunately, I have not been able to reproduce this error on my end.

  • What steps can I take to reproduce this error on my end?
  • Does this occur in a clean, blank project with no additional content or is it limited to one project/template?
  • Can you post the crash logs and callstack here so I can take a look? They can be found at \Unreal Projects\PROJECTNAME\saved\logs.

Hello. For steps, check out the video,

  1. Create Struct.
  2. Create a variable with “Key” type
  3. Create DataTable based on this struct.
  4. Open the DataTable

Yes, this happens on clean project to… I’ve recorded the attached video on a clean project.

Here is a log: CrashTest.log — Yandex.Disk

Those are the steps I took, unfortunately this did not produce a crash as described. Can you send me a sample project where this is occurring so I can take a look?
