Pg: Inserting new data with auto increment column

I am getting error while inserting data to postgres from nextjs api. Error: detail: 'Key (id)=(21) already exists.', I have table with three columns and the API is submitting values as name and status. I am guessing postgres would take care of auto increment. what is the issue here ? 
    id: serial('id').primaryKey(),
    name: varchar('name', { length: 256 }).notNull(),
    status: varchar('status', { length: 100 }).notNull().default('DRAFT')
    id: serial('id').primaryKey(),
    name: varchar('name', { length: 256 }).notNull(),
    status: varchar('status', { length: 100 }).notNull().default('DRAFT')
API 
 const res = await db.insert(dashboards)
            .values({ ...json, status: 'DRAFT' }).returning({ id: dashboards.id })
        return NextResponse.json(res, { status: 200 })
 const res = await db.insert(dashboards)
            .values({ ...json, status: 'DRAFT' }).returning({ id: dashboards.id })
        return NextResponse.json(res, { status: 200 })

If the data you're passing to insert has an id field, it will be sent to the database That's why you're getting the error

No, I did not include ID field in json data. This was another weird issue from poatgres Aurora. I have table with 25 records, manually uploaded using csv file. For some reason, database was considering 21 as latest available auto id. I tried 4 times to push the data from API and it failed. It finally reached 26 and API call was success. It is working fine now. I have no idea what caused auto increment to fail from db side.
