Postgrest inserting json array results in stringified array

I'm trying to insert a an array of objects as a json array but it always ends up being strinfied if it would be just a json then i can do sql${recipeData.notes}::jsonb` but that doesn't work with arrays (cannot cast type record to jsonb`)

hey! I noticed the same issue, having a jsonb doesn't save the array, but just a string instead. I have my column defined like this:

readByJson: jsonb('read_by').$type<string[]>(),

readByJson: jsonb('read_by').$type<string[]>(),

any way to make it save an actual array instead of the string?

i ended up using a custom json field

export const customJsonb = <TData>(name: string) =>
  customType<{ data: TData; driverData: string }>({
    dataType() {
      return "jsonb";
    },
    // @ts-expect-error https://github.com/drizzle-team/drizzle-orm/issues/1511#issuecomment-1824687669
    toDriver(value: TData) {
      return value;
    },
  })(name);

// schema
notes: customJsonb<Array<RecipeNote>>("notes"),

export const customJsonb = <TData>(name: string) =>
  customType<{ data: TData; driverData: string }>({
    dataType() {
      return "jsonb";
    },
    // @ts-expect-error https://github.com/drizzle-team/drizzle-orm/issues/1511#issuecomment-1824687669
    toDriver(value: TData) {
      return value;
    },
  })(name);

// schema
notes: customJsonb<Array<RecipeNote>>("notes"),

yeah that works or use jsonb objects instead if arrays
