Error using Web Crypto API in wrangler 3.1.0

I'm having trouble with Web Crypto API. The error object thrown is not readable by logging. Anyone else experiencing a similar issue? Any ideas?

DOMException {
  stack: undefined,
  code: undefined,
  name: undefined,
  message: undefined
}

DOMException {
  stack: undefined,
  code: undefined,
  name: undefined,
  message: undefined
}

Can you share a snippet of code that can trigger this?

const keyData = 'IZGpRVnehcd1X/eCIbXBkQTTCrT4W6VvCr1wfWqrtZ4='
const data = Uint8Array.from(atob(keyData), (c) => c.charCodeAt(0))
const algorithm = { name: 'AES-GCM' }
crypto.subtle.importKey('raw', data, algorithm, false, [
    'encrypt',
    'decrypt',
  ])

const keyData = 'IZGpRVnehcd1X/eCIbXBkQTTCrT4W6VvCr1wfWqrtZ4='
const data = Uint8Array.from(atob(keyData), (c) => c.charCodeAt(0))
const algorithm = { name: 'AES-GCM' }
crypto.subtle.importKey('raw', data, algorithm, false, [

    'decrypt',
  ])

hmm. i think it was bad key data but not sure. we've recently updated wrangler and i was using the same key data but a fresh one just works fine
