          mongoc_apm_command_failed_get_reply (
             const mongoc_apm_command_failed_t *event);

       Returns  the  server's  reply  to a command that failed. The reply contains details about why the command
       failed. If no server reply was received, such as in the event of a network error, then  the  reply  is  a
       valid  empty BSON document. The data is only valid in the scope of the callback that receives this event;
       copy it if it will be accessed after the callback returns.
