How to make an entity keep the player as it's owner when it transforms?

[frank crystal]

Maybe you spelled it wrong?
"keep_owner": true

[crystal mica]

unfortunatly i don't think thats the problem
"minecraft:transformation": {
"into": "dragonreign:teenflaming_infernowing<spawn_cold>",
"transformation_sound": "convert_to_frog",
"keep_owner": true
