…filerHandler - Introduced standardized error details capturing in IntermediateStepPayload with ErrorDetails model. - Updated Context class to emit success or error events based on function execution outcomes, including detailed error metadata. - Enhanced LangchainProfilerHandler to handle LLM and tool errors, pushing error events with relevant details to the step manager. - Added EventStatus enumeration to track the status of intermediate steps, improving observability in processing flows. This ensures proper nesting of spans, event in the event of tool call/llm/function invocation failures Signed-off-by: Matthew Penn <[email protected]>
