Crash in inspector when selecting a database asset

[maarten-abbey]

I select a database asset, such as the provided TMPEffects/Resources/Databases/ShowAnimationDatabase.asset. The inspector shows nothing, and an error message is posted to the console.

TargetParameterCountException: Number of parameters specified does not match the expected number.

(etc)

The issue is in the line return getDrawerMethod.Invoke(type, new object[] { type }) != null; in SCEditorUtility.cs. For me, this is within the #if UNITY_2022_3_OR_NEWER brackets.

I've added a try around this line, returning a false in the catch, and that solves the issue for me.

I have a clean installation of TMPEffects set up from just a few days ago.
I use the next upcoming version of Unity, version 2023.3.0b10. I believe this version branch will at some point be part of "Unity 6".

Weird... I guess the method signature was changed again.
Can you go ahead and check how many parameters it expects and which ones?

[Luca3317]

Bump

[maarten-abbey]

I tried looking into this, but I'm not exactly sure how this method is to be used.

When I "F12" getDrawerMethod.Invoke, its header seems to be:
public object Invoke(object obj, object[] parameters);
In my case, the 'type' variable and the new object[] { type } variable is a System.String.

But maybe this is what's going wrong: this line is executed because getDrawerMethod.GetParameters().Length is not 2. Maybe it expects it to be 1 - but it is actually 3. See here:

Hope this helps!

[Luca3317]

Seems like they did add another parameter then. I tried replicating this on the Unity6 preview but didnt run into this issue.

I've added a try around this line, returning a false in the catch, and that solves the issue for me.

That class is part of teh SerializedDictionary package, so I didnt really look at it besides when I ran into the issue of it expecting two instead of one parameter on 2022 and above -- does everything still look right visually in the inspector when you just return false, specifically the databases and SceneCommands / SceneAnimations fields on the TMPWriter / TMPAnimator respectively?

Also, can you go ahead and test what happens if you pass in the boolean outside of the array? So
getDrawerMethod.Invoke(type, new object[] { type }, isPropertyManagedReferenceType )

Bump

[maarten-abbey]

I'll try this when I get back on my project, hopefully later this week.

[maarten-abbey]

That doesn't work, the only legal headers in my version are:

public object Invoke(object obj, object[] parameters);

and

public abstract object Invoke(object obj, BindingFlags invokeAttr, Binder binder, object[] parameters, CultureInfo culture);

I've updated to 0.1.5 (I think that's right, even though the tag in git says 1.0.5), I've thrown away my /Library/ folder just in case. That didn't change anything.

This is what I'm seeing if I just return false from my try/catch:

Of course, I'm not exactly sure what I'm supposed to see, but I guess that all looks okay?

Let me know if I can help further testing.

[Luca3317]

Yeah, those all look right. I guess Ill add a return false as a fallback for when none of the signatures match the cases.

Only other idea I have without testing it myself is to do
getDrawerMethod.Invoke(type, new object[] { type, new object[0], isPropertyManagedReferenceType });
If you could give this one a try. If it doesnt work I think Ill just add the false fallback to the existing cases for now.

Fark, I messed up the versioning. Next version will be 1.0.6 then :D

Not using this package (but I am using your fork of SerializedDictionaries) and tested this.

I got the following ArgumentException:

ArgumentException: Object of type 'System.Object[]' cannot be converted to type 'System.Type[]'.

Changing new object[0] to new Type[0] as follows:

return getDrawerMethod.Invoke(
                            type,
                            new object[] { type, new Type[0], isPropertyManagedReferenceType }
                        ) != null;

Has prevented any further errors.
I've made a quick PR Luca3317/SerializedDictionary#1 with this change

Interesting! What version of Unity are you on? Same as @maarten-abbey?

I'm on version 6000.0.23f1 and having this problem.

Your previous fix was working fine for me on 2023.3.40f1, and I upgraded to Unity 6 the other day and the bug came back, so I assume it's from the same cause as OP
