in the examiner's report it says: A common misconception was to use the de Broglie wavelength and the energy expression for a photon instead
Why couldn't you do this?

The question is about electrons, not photons, which is why you can't use the energy expression for a photon.

but isn't the energy of a photon equal to the energy of the electron

No. An electron is a lepton; a photon is a quanta of energy, and can have the same energy as an electron, but not necessarily.

but energy is conserved in the photoelectric effect.

The question had nothing to do with the photoelectric effect - it was about moving an electron through an electric field or something.
