Hi all, I solved my problem from yesterday… I was getting this error:

{
  "error": {
    "code": "SYNTAX_ERROR",
    "message": "org.mozilla.javascript.EcmaError: SyntaxError: Unsupported number format: ------ (INVOCATION_WRAPPER$sys#26)."
  }
}

Once I removed that content-header as JSON and just sent it as plain text it worked.
