Problem
When integrating Hipchat Server/Data Center with Jira, Confluence or Bitbucket Server, and after the installation is approved from the Hipchat side, the install fails with this warning in the UI (Bitbucket is used in this example):
Error encountered creating your Hipchat link
Something went wrong integrating Bitbucket and Hipchat. We probably had trouble connecting to the Hipchat server. Check that the connection between your server and Hipchat is working correctly and try again.
Try uninstalling the existing integration from Hipchat before trying again.
Diagnosis
Check for this exception in the Jira/Confluence/Bitbucket log:
2017-09-21 08:00:53,540 WARN [http-nio-7990-exec-10] admin @D031DYx480x3133x0 t6k92o 134.76.126.13,0:0:0:0:0:0:0:1 "POST /rest/hipchat/integration/latest/installation/complete HTTP/1.1" c.a.p.h.rest.HipChatLinkResource Installation failed. com.sun.jersey.api.client.ClientHandlerException: com.sun.jersey.api.client.ClientHandlerException: A message body writer for Java type, class com.sun.jersey.api.representation.Form, and MIME media type, application/octet-stream, was not found com.sun.jersey.api.client.ClientHandlerException: com.sun.jersey.api.client.ClientHandlerException: A message body writer for Java type, class com.sun.jersey.api.representation.Form, and MIME media type, application/octet-stream, was not foundCause
The root cause of the issue is unknown. We've seen it occurring following an upgrade when the integration is also updated and we suspect it's related to the old plugin cache.
Workaround
On the Jira/Confluence/Bitbucket side:
- Go to Admin > Manage add-ons
- Search for Hipchat in the system add-ons
- Disable all three Hipchat plugins
- Enable all three plugins again
