Hi — thanks for opening this issue!

Before we dig deeper, could you help us narrow down what’s happening? A few clarifying questions:

• Does this error occur every time you call track_openai(...) / use the OpikUsage functionality, or is it intermittent / under certain conditions?
• Can you share a minimal reproducible example (i.e. the smallest snippet of code) that reliably triggers this ValueError?
• Which version(s) of Python, opik, and any related dependencies are you using?
• Do you see a full stack trace or error log (beyond the message “Failed to build OpikUsage …”) that could point to where it fails internally?
• Have you ever had this functionality working correctly (i.e. in a previous version or environment)? If so, what changed (library upgrade, config changes, etc.)?

With those details, we’ll be in a much better position to diagnose what’s going wrong and propose a fix
