I’m unable to modify Data row using the following SQLAlchemy statement:

stmt = (
                update(models.Data)
                .values(
                    custom_columns=(
                        func.coalesce(
                            func.jsonb_set(
                                func.jsonb_set(
                                    cast(models.Data.custom_columns, JSONB), 
                                    '{archived}', 
                                    cast(
                                        models.Data.custom_columns['archived'], 
                                        JSONB
                                    ).op('||')(
                                        func.jsonb_build_object(
                                            old_key, 
                                            cast(
                                                models.Data.custom_columns['fields'][old_key], 
                                                JSONB
                                            )
                                        )
                                    )
                                ),
                                '{fields}', 
                                cast(
                                    cast(models.Data.custom_columns, JSONB)['fields'], 
                                    JSONB
                                ).op('-')(old_key)
                            ),
                            cast(models.Data.custom_columns, JSONB)
                        )
                    ),
                    updated_at=func.now()
                )
                .where(
                    cast(models.Data.custom_columns, JSONB)['fields'].has_key(old_key)
                )
                .where(models.Data.project_id == project_id)
            )

Can someone help?

Tried to delete key, value from “fields” inside “custom_columns” and create “archived” inside custom_columns and add deleted key, value in “archived”
