[Unet] Error: Assertion failed on expression: 'asset->mainRepresentation.type == TypeOf<GameObject>()' on build Standalone

Networking

-

This happens on all Multiplayer projects upgraded from 5.4. If you remove Library folder - this problem will gone. If you change Player object (for example remove some component) - this problem will gone.

2. How we can reproduce it using the example you attached
1 Open attached project and scene "sc1"
2 Press in menu File->Build and Run, select Standalone as build target and set name for the build and press "Build and Run"-button
Actual result: in the middle of the build process - this error should appear:
"Assertion failed on expression: 'asset->mainRepresentation.type == TypeOf<GameObject>()'
UnityEditor.BuildPlayerWindow:BuildPlayerAndRun()"

3 Find Player object prefab (it is called "Cube") in Project view and remove some component
4 Try to "Build and Run" again - it will be built without errors

    Deleting Library Folder DOES NOT make you RESTART

    1) Exit Unity.
    2) Delete or move the directory to a safe location.
    3) Run Unity
    4) It will REBUILD the Library Folder.

    Deleting your library doesn't restart your project - it's just the unity cache files - all of "your project" is in the assets folder.

    Yes there is. I just fixed the issue by opened the [Camera Rig], Camerea(Head), Camera (Eye), and then pressed on collapse. The error is gone. GL all.

    It came out this issue when I using EditorPrefs.DeleteAll ( ).
    Please fix it.

    Happens to me on Windows build. Nothing out of the ordinary ... we're a mplayer game, though. Not sure if that makes a diff

    The issue occurs for me as well.
    I run Unity 5.5.0b2 on Linux, and the issue started appearing after upgrading my project to 5.5.0.b5 and subsequently downgrading back to 5.5.0b2 (as b5 had a couple of annoying bugs).

    I removed $project/Library (the Unity Editor cache directory), which was subsequently re-created on reopening the project, and the error is now gone.

    It seemed to have caused no issues except for the rather cryptic error messages.

    I have the same issue. It doesn't seem to affect the build, but it is strange.

    Is there a fix to this that doesn't require that I delete my entire library, thus starting my project over?..
