fail to cook the request for client invalid result

Summary

I was testing some stuff with scene graph and from a certain point i started to get this message while trying to update/load session and cant figure out whats happening to try and fix it
at first i tought it was due to some material or vfx so i cleared them all and it did not work so i just kept my code and create a new map with no custom asset and it did it again
