NITRO0005Use readValidatedBody for validated request bodies

Why it happens

Raw request input and validation can drift apart when they are separate operations. Nitro and h3 provide validated helpers that keep parsing and validation coupled at the request boundary.

Fix

Use readValidatedBody(event, validator) instead of readBody(event) followed by separate validation.

Example

Keep reading and validation together

Before

export default defineEventHandler(async (event) => {
  const input = await readBody(event)
  const value = validator.parse(input)

  return value
})

After

export default defineEventHandler(async (event) => {
  const value = await readValidatedBody(event, validator)

  return value
})
