NPCs dont attack unless they reach their goal but also error when going for attack?

Testing Style - Studio Local Server with 2 players.

Script Location/Type - Regular script in the NPC

Output - https://ibb.co/8r5BN1m

Outcome - The NPC will spawn, and walk to its goal as expected, however, I want them to break their path if they detect another humanoid and go to attack it, and then continue down its path. Once it reaches its goal however it will stop and then the game will freeze and they'll move slightly and the output shows what I posted in the screenshot and they will stand there without doing anything

Code -
