JSONparse, in _validate_metadata_func(), checks the consistency of the
_metadata_func() function. To do this, it invokes it and makes sure it
receives a dictionary in response. However, during the call, it does not
respect future calls, as shown on line 100. This generates errors if,
for example, the function is like this:
```python
def generate_metadata(json_node:Dict[str,Any],kwargs:Dict[str,Any]) -> Dict[str,Any]:
return {
"source": url,
"row": kwargs['seq_num'],
"question":json_node.get("question"),
}
loader = JSONLoader(
file_path=file_path,
content_key="answer",
jq_schema='.[]',
metadata_func=generate_metadata,
text_content=False)
```
To avoid this, the verification must comply with the specifications.
This patch does just that.
