I test the method aknowledge with the API in PERL an Ruby but they don't work anyway.

I have this message:

JSON-rpc error generation failed. No such error.

I use this

{"jsonrpc":"2.0","method":"event.acknowledge","par ams":

{"eventids":["2053289"],"message":"test comment"}

,"auth":"197a5aca76634427682c839a30ba6cf2 ","id":2}
