Summary

The chat history of some rooms will not load.

Environment

• Hipchat Data Center 3.1.3
• All clients are impacted

Steps to Reproduce

We do not have an exact list of steps to reproduce.

Actual Results

Using the web client, the browser's JavaScript shows errors with:
uncaught exception: badformat
The same error is also visible in the client logs.

Notes

• No server-side errors are logged
• The issue impacts rooms with large messages from integrations, especially message in HTML format
• The root cause of the issue is a bug in raw mode of Punjab, the HTTP to XMPP translator

Workaround

The workaround of the issue is to disable Punjab's raw mode:

1. Comment out the following line in /etc/init.d/punjab:

   PLUGIN_OPTS="$PLUGIN_OPTS --use_raw"
   

   or remove --use_raw if your line looks as follows:

   PLUGIN_OPTS="--white_list=.hipchat.com --site_log_file=/dev/null --route_override=xmpp:127.0.0.1:5222 --use_raw"
   

1. Restart Punjab

   service punjab restart
