[BUG]: Inserting of string timestamps not working in data api

[livingforjesus]

What version of drizzle-orm are you using?

0.29.3

What version of drizzle-kit are you using?

0.19.13

Describe the Bug

If you want to insert or update a record with a timestamp (mode:string)
You got an error which suggested that data api was recognizing it as a string not a timestamp

Inserting when a schema field is as follows:

updatedAt: timestamp('updated_at', { withTimezone: true, mode: 'string' }).notNull().defaultNow(),

A code like this doesn't work in rds data api:

await db.insert(usersTable).values({ name: 'John', updatedAt: new Date().toIsoString() })

Expected behavior

I expect the call to rds to actually work and not give out an error

Environment & setup

No response
