Thank you for reporting this issue. While the documentation does not mention a widespread problem with blank summaries, configuration or prompt issues can sometimes cause this behavior.
Could you please share a recent Call ID where the summary was blank? This will help us review the logs and provide more targeted troubleshooting steps. If possible, also confirm if any recent changes were made to your assistant's summary prompt or model configuration.
For reference, you can find the Call ID in your [Vapi dashboard](
https://dashboard.vapi.ai/calls). Providing this information will help us investigate further and resolve the issue efficiently.
