    Had the same error because there was a canvas scaler component on a nested canvas.
    Happened because i dragged one root canvas into another existing canvas and forgot to delete the canvas and canvas scaler component on the nested one.
    Removing the canvas scaler component fixed it.

    I got this error 5.4.4p2 and it appears to be UI related. I had removed a canvas component from a game object. Then when the game object gets activated at run time, it spits out this error message. Adding the canvas component back to the game object gets rid of the error.

    I receive this error in the Player within Unity, I'm not sure what causes it, and no other info is given.

    Is this a harmless error?
