GetSocketTransform results in error

I have the following code:

			FVector Start = Hero->GetWeaponComponent()->GetSocketLocation(FName("SOCKET_MuzzleFlash"));
			FVector End = Hero->GetCameraBoom()->GetComponentLocation() + Hero->GetFollowCamera()->GetForwardVector() * Range;
			FRotator Rotation = UKismetMathLibrary::FindLookAtRotation(Start, End);

			FGameplayEffectSpecHandle DamageEffectSpecHandle = MakeOutgoingGameplayEffectSpec(DamageGameplayEffect, GetAbilityLevel());

			// Pass the damage to the Damage Execution Calculation through a SetByCaller value on the GameplayEffectSpec
			DamageEffectSpecHandle.Data.Get()->SetSetByCallerMagnitude(FGameplayTag::RequestGameplayTag(FName("Data.Damage")), Damage);

			FTransform MuzzleTransform = Hero->GetWeaponComponent()->GetSocketTransform(FName("SOCKET_MuzzleFlash"));
			MuzzleTransform.SetRotation(Rotation.Quaternion());
			MuzzleTransform.SetScale3D(FVector(1.0f));

The following line breaks my code:

FTransform MuzzleTransform = Hero->GetWeaponComponent()->GetSocketTransform(FName("SOCKET_MuzzleFlash"));

Here is my stacktrace:

Can anyone tell me whats going on?

Have you considered doing a nullptr check before Hero->GetWeaponComponent()?
What if the weapon isn’t assigned and you are just accessing a null pointer?
