If light has no mass, how does gravitational force bend light inwards

In the case of black holes, lights are pulled into by great gravitational force exerted by the dying stars (which forms into a black hole). If light has no mass, how is light affected by gravity?

The energy mass equivalence. What we cassualy refer to as mass is actually the restmass of an object. Light doesn’t have any. But what light has is energy. Thats why sunrays are hot for exmaple.

This energy “converts” to relativistic mass according to the mass energy equivalenze. That relativistic mass is what is influenced by gravity
