Getting error while using Postgresql only

This is how I have set up the database:

database: new Pool({
    connectionString: process.env.DATABASE_URL,
  }),

database: new Pool({
    connectionString: process.env.DATABASE_URL,
  }),

database: new Pool({
    connectionString: process.env.DATABASE_URL,
  }),

database: new Pool({
    connectionString: process.env.DATABASE_URL,
  }),

I used better auth cli to generate and migrate the tables to postgresql.

And when I make an api request to register, I get this error.

{
    "error": "relation \"user\" does not exist"
}

{
    "error": "relation \"user\" does not exist"
}

{
    "error": "relation \"user\" does not exist"
}

{
    "error": "relation \"user\" does not exist"
}
