Hello, one my Structured Output returned an empty json after a call for some reason. It should've been populated with the set fields and informations that was supposed to gather. I wanna understand why that happened and if it will happen again.

To diagnose why your structured output was empty, go to your Vapi dashboard and navigate to Observe > Call Logs, then select the call with ID

019dfb1a-7e7e-7000-8117-ae10658eac5c

. Review the transcript and structured output section to check if the required information was present and if any extraction errors were logged. This will help you pinpoint if the issue was due to missing data, unclear schema descriptions, or another extraction problem. Tip: Update your schema field descriptions for clarity if you notice variables are not being extracted as expected. Source: - [Debugging voice agents](https://docs.vapi.ai/debugging)

That was not helpful. I already debugged the call, all the information was there, the "expected result" provided was extracted from the deprecated Analysis log from the same call, so the information is definetely there. Also, different calls from the past and the future had the Structured Output filled as expected
