Dynamic on conflict definition

[olmohake]

I am struggling to set up the SET part of my on conflict definition dynamically.
Everything else working smoothly, but failing to pass upsert information.
Would welcome any help.

const targetTable = "test"
const columns = ["id", "name", "geometry"]
const onConflict = { keys: ["id"], update: ["name", "geometry"]}

await sql`
  INSERT INTO ${sql(targetTable)} ${sql(data, columns)}
  ON CONFLICT (${sql(onConflict.keys.join(","))}) DO UPDATE
  SET ${sql(onConflict.update.map(column => `${column} = EXCLUDED.${column}`).join(",")};
`
