I tried to make a POST request to /api/v1/accounts, and the returned response code is 200, but the body is empty.

curl --request POST \
  --url http://localhost:8080/api/v1/accounts \
  --header 'Accept: application/json' \
  --header 'Authorization: Bearer ZDNLZME4NTGTYWQ3MC0ZZJJMLWFINMETNZDLMGYYYTBJMTK3' \
  --header 'User-Agent: test' \
  --header 'content-type: application/json' \
