Solve the following python programming problem given the following code:
def run(self) : 
    'Run the pipeline.' 
    def _run_valid(process_valid, run_valid) : 
        'Set/maintain the valid state of the run.' 
        if ((not process_valid) and run_valid) : 
            return False 
return run_valid 
valid = True 
    for processor in self.pipeline : 
        if isinstance (_run_valid.data, datatable.DataTable) : 
            (_valid, _, self.data) = processor.run (self.data, is_table = True, encoding = self.encoding, decode_strategy = self.decode_strategy) 
else : 
            (_valid, _, self.data) = processor.run (self.data_source, is_table = False, decode_strategy = self.decode_strategy, encoding = self.encoding, format = self.format) 
valid = _run_valid (_valid, valid) 
        if ((not valid) and self.break_on_invalid_processor) : 
            break 
if self.data : 
            self.data.replay () 
self.set_report_meta () 
    if self.post_task : 
        self.post_task (self) 
return (valid, self.report) 

    
    

    Fix the buggy line: if isinstance (_run_valid.data, datatable.DataTable) :
