Foreign key reference in drizzle causes type error

In my drizzle schema, I have two tables, users and payment_history, when I try to reference the id of payment_history, it throws a type error Function implicitly has return type 'any' because it does not have a return type annotation and is referenced directly or indirectly in one of its return expressions.. users table and payment_history table have a one to many relation where one user can have many payments. These are my schema definition: users:

export const users = pgTable("users",{
...
   last_payment_id: varchar("last_payment_id").references(() => payment_history.id, { onDelete: "cascade" }),//error
...
})

export const users = pgTable("users",{
...
   last_payment_id: varchar("last_payment_id").references(() => payment_history.id, { onDelete: "cascade" }),//error
...
})

payment_history:

export const payment_history = pgTable("payment_history",{
   id: varchar("id").primaryKey().unique().notNull(),
...
   user_id: varchar("user_id").references(() => users.id, { onDelete: "cascade" }), //fk to users.id where i get type error
})

export const payment_history = pgTable("payment_history",{
   id: varchar("id").primaryKey().unique().notNull(),
...
   user_id: varchar("user_id").references(() => users.id, { onDelete: "cascade" }), //fk to users.id where i get type error
})

and these are the table relations: users:

export const userRelation = relations(users, ({ one, many }) => ({
...
   payment_history: many(payment_history),
...
}))
export const paymentHistoryRelations = relations(payment_history, ({ one, many }) => ({
...
   last_payment: one(users, {    
      fields: [payment_history.user_id],
      references: [users.last_payment_id],
   }),
...
}))

export const userRelation = relations(users, ({ one, many }) => ({
...
   payment_history: many(payment_history),
...
}))
export const paymentHistoryRelations = relations(payment_history, ({ one, many }) => ({
...
   last_payment: one(users, {    
      fields: [payment_history.user_id],
      references: [users.last_payment_id],
   }),
...
}))

👋 Can you try this?

references((): AnyPgColumn => xxxx

references((): AnyPgColumn => xxxx

that works but...how, I tried mentioning the return type like this before:

user_id: varchar("user_id").references(():ReturnTypeOrValue<typeof users.id>  => users.id, { onDelete: "cascade" }), //fk to users.id

user_id: varchar("user_id").references(():ReturnTypeOrValue<typeof users.id>  => users.id, { onDelete: "cascade" }), //fk to users.id

but this gave me a circular reference type error

Did you find this somewhere in the doc?

p o h aOP•6mo ago

no i just figured if the type error is because it has an implicit any type then I should mention the type

the AnyPgColumn is a generic but not mentioned that much in the doc 😬. The reason is https://arc.net/l/quote/bicdfvte

Nothing wrong with your code, just some TS weird issues It hates circular references, so we have to rely on a generic to break it
