Hello everyone
im facing an issue when trying to implement google outh
ive created a route handler (nextjs) to handle the code coming from google.

const userInfo = await sdk.client
        .fetch<Record<string, string> | null>('/google-get-email', { headers })
        .catch((err) => (console.log(err), null))

this function request a custom api route from my medusa backend that get the user email.
here is the code:
export async function GET(request: NextRequest) {
  try {
    const code = request.nextUrl.searchParams
    if (!code) {
      console.error('user didnt provide any code')
      return NextResponse.redirect(new URL('/', request.url))
    }
    const googleToken = await sendCallback(
      Object.fromEntries(request.nextUrl.searchParams.entries())
    )

    const shouldCreateCustomer =
      (decodeToken(googleToken) as { actor_id: string }).actor_id === ''

    console.log(googleToken)
    if (shouldCreateCustomer) {
      //todo make an api request to get the user mail
      const headers = {
        Authorization: `Bearer ${googleToken}`,
      }
      const userInfo = await sdk.client
        .fetch<Record<string, string> | null>('/google-get-email', { headers })
        .catch((err) => (console.log(err), null))

      if (!userInfo?.email) return

      await setAuthToken(googleToken)
      await sdk.store.customer.create(
        {
          email: userInfo.email,
          first_name: userInfo?.given_name,
          last_name: userInfo?.family_name,
        },
        undefined,
        headers
      )
      await sdk.auth.refresh()
      revalidateTag('customer')
      return NextResponse.redirect(new URL('/account', request.url))
    } else {
      console.log('user already registered... ')
      await setAuthToken(googleToken)
      revalidateTag('customer')
      return NextResponse.redirect(new URL('/account', request.url))
    }
  } catch (e) {
    console.error(e)
    // redirect('/?error=' + (e?.message ?? 'no message'), RedirectType.replace)
  }
}

const sendCallback = async (params: Record<string, string>) => {
  let token = ''

  try {
    token = await sdk.auth.callback('customer', 'google', params)
  } catch (error) {
    console.error(error)
    throw error
  }
  return token
}

here the error stack;

I've encountered this problem too. I've been struggling for three days now; the development structure is too confusing.
