column "summary" cannot be cast automatically to type jsonb

Hello! I'm getting this error when running my migrations, I used to have a text field and now it's a jsonb

summary: jsonb("summary").notNull(),

summary: jsonb("summary").notNull(),

How can I resolve this? This is the migration:

ALTER TABLE "merlin_task_results" ALTER COLUMN "summary" SET DATA TYPE jsonb;--> statement-breakpoint
ALTER TABLE "merlin_task_results" ALTER COLUMN "summary" SET NOT NULL;

ALTER TABLE "merlin_task_results" ALTER COLUMN "summary" SET DATA TYPE jsonb;--> statement-breakpoint
ALTER TABLE "merlin_task_results" ALTER COLUMN "summary" SET NOT NULL;

Is there data in the table? I would just rename the column, run migration, rename back to what you want and run migration again. Or just edit the SQL migration file and drop the column and recreate it

Do you think this looks ok?

ALTER TABLE "merlin_task_results" DROP COLUMN "summary";
ALTER TABLE "merlin_task_results" ADD COLUMN "summary" jsonb DEFAULT '{}' NOT NULL;

ALTER TABLE "merlin_task_results" DROP COLUMN "summary";
ALTER TABLE "merlin_task_results" ADD COLUMN "summary" jsonb DEFAULT '{}' NOT NULL;

Do I need this? --> statement-breakpoint
