[BUG] "ArgumentException: method argument length mismatch" on Node inspector

[darthdeusParticipant]

When I click the marked icon in the Node inspector it disappears and throws an error and I have to restart Unity to get it back. Re-opening the canvas window is not enough

Hello again,

What version of Unity are you using please?
There was a recent finding in regards to External Inspector (which is what that button opens) that has been fixed and which may also be the reason behind this error (which as far as I can tell you are using a Unity version of 2020+ ?).
Please try importing the attached package (fix) and let me know if that solves the problem for you.

Thank you.

Worked for me,but after importing this package need to reset layout to default (2020.1.8f1).

Hello,

In the new version just released (3.1.6), this error has been fixed 🙂

Thanks!
