Why did Krishna put a curse on Hanuman?

Krishna did not directly curse Hanuman; rather, it was a misunderstanding related to the story of the Ramayana. In one version, Krishna, in his playful nature, jokingly mentioned that Hanuman would forget his divine powers and glory in the future. This was meant to emphasize Hanuman's humility and devotion, as he would only remember his abilities when they were needed to serve Lord Rama or fulfill his duties. Ultimately, this "curse" served to highlight Hanuman's selflessness and unwavering devotion.
