langwatch trace input not showing user chat input

[snova-jorgep]

Bug Description

In langwatch when having a complex flow with multiple agents and components, the input of the trace shows the input of one of the tools and not the user input

also the LLM traces don't contain usage metrics

Reproduction

deploy a local langflow, add the LANGWATCH_API_KEY to the .env file, and run the financial assistant template

the input of the traces shown is the input of one of the tools used by the agent instead of the user input

Expected behavior

input in langflow trace should match with the user chat input, and llm traces are expected to shown usage metrics and metadata returned by the models

Who can help?

The issue you're experiencing with Langflow, where the input trace shows the input of one of the tools instead of the user input, might be related to how Langflow determines which input to display in the trace. Langflow uses the flowPool and flowPoolId to track the flow state and determine the specific output to display. This logic ensures that the correct output is displayed based on the current state of the flow and the specific output name ^[1].

Regarding the absence of usage metrics in LLM traces, Langflow is supposed to capture usage metrics and metadata through the TracingService class, which utilizes the LangWatchTracer. This includes recording inputs, outputs, and metadata for each trace ^[2].

To address these issues, you might want to verify the configuration and ensure that the LANGWATCH_API_KEY is correctly set up in your environment. Additionally, reviewing the flow setup to ensure that the user input is correctly mapped and traced might help resolve the input mismatch issue. If the problem persists, it could be a bug in the current version (1.1.5) that might need further investigation or a potential update from the maintainers.
