Creating snapshot via API fails

[wiad]

Creating a snapshot via api fails with

{
  "error": {
    "message": "missing required parameter memory"
  }
}

Creating snapshot via GUI works as expected.

Have you tried specifying the include_ram-parameter?

Thank you, with the include_ram parameter added it works again. It doesnt matter if I set it to true or false, but without it I get the error message. Looking at the code there is a default value but this does not seem to work then?
