I get this Error:

NullReferenceException: Object reference not set to an instance of an object

Editor Version 2022.3.16f1 (latest 2022 LTS) (now updated to 2022.3.27f1, as corrected by @DevDunk )

I do not understand what is going on here, I think this is a bug.
I can still create a subgraph, create the code inside it… but it is very inconvenient to do when there is a tool that should work, but does not.

Thanks in advance

That definitely is not the latest LTS. That would be 2022.3.27. Give it a shot
if that does not work, file a bug report and link this thread in it

Sorry, I thought Unity tells you when there’s an update. I’ll update now

4

yep, the issue is still there after updating. I’ll try a brand new project and see if it works differently from my converted one, if not then I’ll file a bug report

brand new project does not work, filing bug

sorry for this question, but how do I share the Bug Report on this thread?

In Unity click Help - Report a bug

You can just type the bug report ID number here if anyone wants to reference it or when unity staff reads it

Thanks, bug ID IN-75743

Are there any updates? I can’t find the issue in issue tracker by ID

10

Unity says it’s fixed now

11

In there words:

That’s not the newest version, I don’t think

14

Yeah true, just observing that the ‘2022.3.x not having the issue’ is not correct. I’ll try updating to the newest, but if their resolution was ‘won’t fix’, I doubt it will have magically dissappeared…

15

Yeah - Resolution Notes: This issue doesn’t exist in this version. Is not correct, unless it was fixed as I uploaded the bug report

16

Same here, version 2022.3.46f1, which is not the lastest but almost and there is nothing in the .47 and .48 saying that they fixed this.

Any workaround?

EDIT: The same error happens when copying properties from one (sub)graph to another, which is probably the source of the original problem.

Humm, that’s probably the issue then. Maybe file a bug report?
