Native chat/internal chat doesn't show messagesIssue For a user, when they open the right side chat page under the homepage, nothing shows up. Not even the heading and plus (+) icon to start a new conversation. CauseThis can be caused by a corrupted chat record. If any of the active chat for that particular user got corrupted, it provides the following error: txid=<transaction_id> SEVERE *** ERROR *** java.lang.ArrayIndexOutOfBoundsExceptionResolutionTo resolve this issue, figure out which chat record is causing the issue by deactivating the active chats one after another for the affected user. Once the affected chat is found, change the state of that record from admin to inactive.
