I'm running the ncmount app from coretutorials.
in using the APIDOCs I found that I could issue ncmount:list-nodes from Safari but got error 500 from Firefox.
Using Postman to manually issue the RPC works ok:
{
"output":
}
but if I remove the headers (Accept: application/json and Content-Type application/json) from my Postman request it fails:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>
<title>Error 500 Server Error</title>
</head>
<body>
<h2>HTTP ERROR 500</h2>
<p>Problem accessing /restconf/operations/ncmount:list-nodes. Reason:

seems that the issue is the lack of a Content-Type: header (even though there's no content per-se as this is an RPC with no input parms)
so I then tried an RPC that took a parameter (ncmount:show-node).
that worked fine from both firefox and safari in apidocs.
