UObject cannot validate an argument I pass it using FObjectFinder.

I’m trying to just change the basic animation flipbooks in the C++ 2D Sidescroller template to get started with this engine. My code is as follows:

const FVector PlayerVelocity = GetVelocity();
const float PlayerSpeedSqr = PlayerVelocity.SizeSquared();

// Are we moving or standing still?
/*UPaperFlipbook* DesiredAnimation = (PlayerSpeedSqr &gt; 0.0f) ? RunningAnimation : IdleAnimation;
if( GetSprite()-&gt;GetFlipbook() != DesiredAnimation     )
{
    GetSprite()-&gt;SetFlipbook(DesiredAnimation);
}*/

// Running or standing still

if (PlayerSpeedSqr &gt; 0.0f) {
    GetSprite()-&gt;SetFlipbook(ConstructorHelpers::FObjectFinder&lt;UPaperFlipbook&gt;(TEXT("/Game/2DSideScroller/Sprites/MyRunningFrames/RunAnimation")).Object);
}
else {
    GetSprite()-&gt;SetFlipbook(ConstructorHelpers::FObjectFinder&lt;UPaperFlipbook&gt;(TEXT("/Game/2DSideScroller/Sprites/MyIdleFrames/IdleAnimation")).Object);
}

However I am getting the error:

I have been following a tutorial on how to do this and cannot see anything immediately wrong with my code.
I know this might be a nooby question but I cannot find any resources online for this problem.
Thank you
