Hey @areejwork017! 😄 Long time no see in the digital corridors of code. How's the coding world treating you lately? Based on the error messages you're encountering and the code you've provided, it seems like the issue might be related to the output from the LLM predictor not being a valid JSON. This is causing the This issue has been encountered before in the LlamaIndex repository. In a similar issue, the user was advised to add error handling to parse the output as JSON and catch any JSONDecodeError. If a JSONDecodeError is caught, you can log the error and return None. Here's how you can modify the from json import JSONDecodeError
def generate(self, tools, query):
tools_str = self._tools_to_str(tools)
query_str = self._query_to_str(query)
prediction = self._llm_predictor.predict(
prompt=self._prompt,
tools_str=tools_str,
query_str=query_str,
)
try:
parse = self._prompt.output_parser.parse(prediction)
except JSONDecodeError:
logger.warning(f"LLM predictor output is not a valid JSON: {prediction}")
return None
parse = cast(StructuredOutput, parse)
return parse.parsed_output This modification will catch the JSONDecodeError and log a warning message if the output from the LLM predictor is not a valid JSON. It will then return None, which should prevent the ValueError from being raised in the Please note that this is a workaround and may not fully resolve the issue. The root cause of the issue is likely that the LLM predictor is not returning a valid JSON. You may need to investigate why this is happening and fix it at the source. As for the second error message you're encountering, it seems to be related to the I hope this helps! If you have any other questions or need further clarification, feel free to ask. Sources

I'm new to RouterQueryEngine on Llama Index and I've been following the steps in the documentation here. But whenever I run the query engine cell, I keep getting this error:
Can someone explain why this is happening? Also, when I provide a query like "What is the summary of the 'context name'?", I get this error:
Any help would be appreciated. Thanks!
