Solve the following python programming problem given the following code:
def _process_async_error(self, resp_body, error_class) : 
    '
        The DNS API does not return a consistent format for their error
        messages. This abstracts out the differences in order to present
        a single unified message in the exception to be raised.
        ' 
    def _fmt_error(err) : 
        details = err.get ('details', '').replace ('
', ' ') 
        if (not details) : 
            details = err.get ('message', '') 
return ('%s (%s)' % (details, err.get ('code', ''))) 
error = resp_body.get ('error', '') 
    if ('failedItems' in error) : 
        faults = error.get ('failedItems', { 
            
}).get ('faults', []) 
        msgs = [_fmt_error (msg) for fault in faults] 
        msg = '
'.join (msgs) 
else : 
        msg = _fmt_error (error) 
raise error_class (msg) 

    
    

    Fix the buggy line: msgs = [_fmt_error (msg) for fault in faults]
