Migration issue with PostgresSQL

I'm trying to migrate

export const postLikeTable = pgTable(
  "post_like",
  {
    postId: text("post_id")
      .references(() => postTable.id, { onDelete: "cascade" })
      .notNull(),
    userId: text("user_id")
      .references(() => userTable.id, { onDelete: "cascade" })
      .notNull(),
  },
  (self) => ({
    pk: primaryKey({ columns: [self.postId, self.userId] }),
  })
);

export const postLikeTable = pgTable(
  "post_like",
  {
    postId: text("post_id")
      .references(() => postTable.id, { onDelete: "cascade" })
      .notNull(),
    userId: text("user_id")
      .references(() => userTable.id, { onDelete: "cascade" })
      .notNull(),
  },
  (self) => ({
    pk: primaryKey({ columns: [self.postId, self.userId] }),
  })
);

But it says PostgresError: foreign key constraint "post_like_post_id_post_id_fk" cannot be implemented code: "42804"

My post and user table looks like

export const postTable = pgTable("post", {
  id: uuid("id").defaultRandom().primaryKey(),

  title: varchar("title", { length: 50 }).unique().notNull(),
  content: varchar("content", { length: 1000 }).notNull(),
  price: doublePrecision("price").default(0),

  createdAt: timestamp("created_at", {
    precision: 2,
    withTimezone: true,
  }).defaultNow(),

  userId: text("user_id")
    .references(() => userTable.id, { onDelete: "cascade" })
    .notNull(),
});

export const postTable = pgTable("post", {
  id: uuid("id").defaultRandom().primaryKey(),

  title: varchar("title", { length: 50 }).unique().notNull(),
  content: varchar("content", { length: 1000 }).notNull(),
  price: doublePrecision("price").default(0),

  createdAt: timestamp("created_at", {
    precision: 2,
    withTimezone: true,
  }).defaultNow(),

  userId: text("user_id")
    .references(() => userTable.id, { onDelete: "cascade" })
    .notNull(),
});

export const userTable = pgTable("user", {
  id: text("id").primaryKey(),
  username: varchar("username", { length: 20 }).notNull().unique(),
  role: userRoleEnum("role"),
  cash: doublePrecision("cash").default(0),
});

export const userTable = pgTable("user", {
  id: text("id").primaryKey(),
  username: varchar("username", { length: 20 }).notNull().unique(),
  role: userRoleEnum("role"),
  cash: doublePrecision("cash").default(0),
});

Found the issue. It was happening because of incompatible types: text and uuid
