Custom Dataset | Still Raise Error while handling errors in _generate_examples
### Describe the bug

I follow this [example](https://discuss.huggingface.co/t/error-handling-in-iterabledataset/72827/3) to handle errors in custom dataset. I am writing a dataset script which read jsonl files and i need to handle errors and continue reading files without raising exception and exit the execution.

```
def _generate_examples(self, filepaths):
        errors=[]
        
        id_ = 0
        for filepath in filepaths:
            try:
                with open(filepath, 'r') as f:
                    for line in f:
                        json_obj = json.loads(line)
                        
                        yield id_, json_obj
                        id_ += 1
            except Exception as exc:     
                logger.error(f"error occur at filepath: {filepath}")      
                errors.append(error)
```

seems the logger.error is printed but still exception is raised the the run is exit.
