7 month old hates solids 😭

My 7mo (birth weight 2.5 kg, current weight 7.8kg) is a active and happy kid. However, he hates solids. All types. Have tried so many and failing to make him enjoy anything. I feel his weight is also on a lower side but Paedetrician says its fine. He is an exclusively breastfed kid and I had hoped that once he starts solids I would get some relief. Any 7mo moms here? Is his weight okay? How to make him enjoy food and gain some weight in the process.
