Netcode crashes due to 'reading past the end of the buffer'

[2shady4u]

Describe the bug
I have an animator on my Player prefab that I would like to sync over the network. As a result I've added a NetworkAnimator component to my Player and I've dragged & dropped my Animator in the correct slot.

Even when I don't sync anything (I don't select any of my Animator parameters), the game crashes when I run it due to following error:

OverflowException: Reading past the end of the buffer

Environment (please complete the following information):

• OS: Windows 10
• Unity Version: 2020.3.21f1
• Netcode Version: 1.0.0-pre.2

Anyone know what's going on here? Am I doing something wrong?
This used to work without any issue with MLAPI.

Maybve this is the same issue i as having. Seems fixed in in master #1327
the way I made it work is actually copying the code of NetworkAnimator into my own MyNetworkAnimator and commenting out those "if (valueInt != oldValue)" statements in WriteParameters

Fixed in 1.0.0-pre.3. Please re-open if the issue persists in the latest version.

Hi, I'm having the same issue in 1.0.0-pre.6. See the screenshots below please.

Could you please reopen and help me?

@rafante That is not the same issue (this one is related to NetworkAnimator). Please file a new support request issue with appropriate detail about your situation.
