"Cannot find primary key" error for postgres tbl

I’m trying to run platformatic on an existing postgres db by setting connection string directly and bypassing migration. on npx platformatic db start I get the following error Error: Cannot find primary key for Advert entity.

The adverts table has the following DDL:

-- idkdb.adverts definition

-- Drop table

-- DROP TABLE idkdb.adverts;

CREATE TABLE idkdb.adverts (
	id serial4 NOT NULL,
	image_url varchar NOT NULL,
	thumbnail_url varchar NOT NULL,
	name varchar NOT NULL,
	description varchar NOT NULL,
	link varchar NOT NULL,
	last_displayed timestamp NULL,
	created_at timestamp NOT NULL DEFAULT now(),
	CONSTRAINT adverts_pkey PRIMARY KEY (id)
);

Any idea what could be causing this?

Discussed with @ivan-tymoshenko offline. This was caused by using a connection string for a user without DDL permissions. See https://github.com/platformatic/platformatic/issues/161 for follow-up.

While troubleshooting, we ran into another a similar “Cannot find primary key” error. In this case, the table only has a foreign key without a primary key:

-- idkdb.documents_metadata definition

-- Drop table

-- DROP TABLE idkdb.documents_metadata;

CREATE TABLE idkdb.documents_metadata (
    document_id int4 NOT NULL,
    star bool NOT NULL DEFAULT false,
    starers_uuid int4 NULL,
    net_likes int4 NOT NULL DEFAULT 0,
    updated_at timestamp NOT NULL DEFAULT now(),
    CONSTRAINT documents_metadata_document_id_fkey FOREIGN KEY (document_id) REFERENCES idkdb.documents(id) ON DELETE CASCADE
);
CREATE UNIQUE INDEX documents_metadata_document_id_idx ON idkdb.documents_metadata USING btree (document_id);

-- Table Triggers

create trigger documents_metadata_set_updated_at_timestamp before
update
    on
    idkdb.documents_metadata for each row execute function set_updated_at_timestamp();

We won’t have endpoints that return entity by id, but we still can have an endpoint that return all entities. WDYT?

Indeed, it would essentially be a read-only table. What’s interesting is that you could still use it for nested references.
