json.dumps in aggregate_responses throws exception if object contains UUIDs #449
Description
I have a weaviate vector store where one property (article_id) is of type UUID.
Adding langtrace to my project has bricked my retriever because the questions.query.near_text call now raises an exception because the object is not JSON serializable.
This issue is cause by the "aggregate_responses" function in the "langtrace_python_sdk/instrumentation/weaviate/patch.py" uses json.dumps.
using return json.dumps(all_responses, default=str) would fix this issue.
Alternativeley you could let the user specify a json encoder when initializing langtrace like it is possible with flask: https://gist.github.com/claraj/3b2b95a62c5ba6860c03b5c737c214ab
