async Nitro middleware

Hey, can Nitro middleware be async? I'm trying to figure it out but I get Nuxt error 402 HTTP method is not allowed. when I make middleware async.

can you show an example what you are doing in that middleware?

export default defineEventHandler(async event => {
  const body = await readBody(event)

  try {
    JSON.parse(body)
  }
  catch {
    throw createError({
      statusCode: 415,
      statusMessage: 'Body is not JSON.',
    })
  }
})

export default defineEventHandler(async event => {
  const body = await readBody(event)

  try {
    JSON.parse(body)
  }
  catch {
    throw createError({
      statusCode: 415,
      statusMessage: 'Body is not JSON.',
    })
  }
})

If you use readBody your route will throw a 405 in case you use any request method which does not can contain a Body e.g. a GET. Try so send a POST, PUT or some similar with body.

export default defineEventHandler(async (event) => {
    if (event.method === 'GET') {
        // do nothing, since we do not have a body in GET
        return
    }

    try { 
      const body = await readBody(event)
    } catch {
       // your logic
    }
})

export default defineEventHandler(async (event) => {
    if (event.method === 'GET') {
        // do nothing, since we do not have a body in GET
        return
    }

    try { 
      const body = await readBody(event)
    } catch {
       // your logic
    }
})
