New subject: [OpenSER-Users] OpenXcap exception: TypeError in twisted.web2.stream.IByteStream

Hello,

I have the same error as Gregorio on my installation, I am running OpenSER
1.3 and my XCAP client is eyeBeam².

Thanks in advance for your help,

Antoine

  Hi all.

 I get an exception in openXcap when I send a GET to retrieve the resources
 file.

 I explain the process I followed:

 ----->Send GET to openXcap.

 <----Receive 404, because there is not file.

 -----> Send PUT to openXcap. The body contains a resource-list.xmldocument 'with
no data':

 Body;

 <?xml version='1.0' encoding='UTF-8'?>

 <resource-lists xmlns='urn:ietf:params:xml:ns:resource-lists'
 xmlns:cp='urn:ietf:params:xml:ns:copycontrol'>

 <list></list>

 </resource-lists>

 <----Receive 200 OK. So openXcap likes my document.

 -----> Send GET to openXcap.

 <---- Receive 500 "An error occurred rendering the requested page. More
 information is available in the server log". So the same document that was
 accepted in the PUT throws an exception.

 The server log says:

 Oct 30 15:01:55 localhost openxcap[2791]: [-] Exception rendering:

 Anyone know what is wrong?

 Thanks and best regards.
