Filtering for json, but sea_orm filters for jsonb instead. Postgresql

[hldup]

I have an enum that I save into my postgresql database as a Json value with serde_json.

pub enum BelongsTo {
    User(Uuid),
    Group(Uuid),
}

When I try to search for it I get an error from the databasa saying I cannot compare json = jsonb. I don't really understand why its trying to query with a JsonBinary instead of normal Json.

    crate::entities::job::Entity::find()
            .filter(entities::job::Column::BelongsTo.eq(serde_json::to_value(belongs_to).unwrap()))
            .all(db)
            .await

Query Error: error returned from database: operator does not exist: json = jsonb

I have also double checked, and indeed my type is json in the entities.
Any ideas why this could be happening?
