I am getting this error with this api route code.

import { analyzeTrackSegment } from '@/lib/bedrock'
import { NextRequest } from 'next/server'

interface ResponseBody {
  images: string[]
  startIndex: number
  endIndex: number
  scale: number
}

export async function POST(request: NextRequest): Promise<Response> {
  const { images, startIndex, endIndex, scale }: ResponseBody = await request.json()
  const imagesData: { contentType: string; imageData: string }[] = []

  for (const image of images) {
    const contentType = image.split(';')[0].split(':')[1]
    const imageData = image.replace(/^data:image\/(jpeg|png);base64,/, '')
    imagesData.push({ contentType, imageData })
  }

  const result = await analyzeTrackSegment({ startIndex, endIndex, imagesData, scale })
  if (result) return new Response(JSON.stringify(result), { status: 200 })
  else return new Response('Failed to analyze track segment', { status: 500 })
}

I've seen other people have this error with DELETE but im using POST so not sure why its happening.

It also only happens on the first request, and any subsequent request if I modify the code of that api route and refreshes the module in dev mode.

Any ideas?
