Hey ! I have an assistant working in VAPI, with all her prompts, in Structured data also have a prompt which must appear in call logs after the transcript is done, but in analysis the data optput is empty. How can a fix it? A call ID for example: c76acbb8-cb39-46ed-96d0-fe3ae499657c Prompt: https://cdn.discordapp.com/attachments/1379825752111059175/1379825752337547345/image.png?ex=6841a65f&is=684054df&hm=896f317e0eb5691d734621b665ae5a6149e6b5ce4d4c58a5120420274e06ae35&

Try this: Double-check that your structured data schema is included as valid JSON in your assistant's configuration. For your use case, it should look like:

json
{
  "structuredDataSchema": {
    "type": "object",
    "properties": {
      "TamizajeInicial": {
        "type": "object",
        "properties": {
          "CriteriosInclusion": {
            "type": "object",
            "properties": {
              "PreguntasRespuestas": {
                "type": "object",
                "properties": {
                  "edad_18_60": { "type": "boolean" },
                  "reside_bogota_urbano": { "type": "boolean" },
                  "conectividad_internet": { "type": "boolean" },
                  "sintomas_atenuados_post_hosp": { "type": "boolean" },
                  "red_apoyo_funcional": { "type": "boolean" },
                  "cuidador_mismo_domicilio": { "type": "boolean" },
                  "perdida_capacidades_impide_metas": { "type": "boolean" },
                  "consumo_sustancias_problema": { "type": "boolean" }
                }
              }
            }
          }
        }
      }
    }
  }
}

Paste this into your assistant's

analysisPlan

and make sure your prompt and schema are both set. If the transcript contains the relevant info, the structured data should appear in the analysis output. Source: - [Vapi Call Analysis Documentation](https://docs.vapi.ai/assistants/call-analysis#structured-data-schema)

still not working

Hey, you need to set the analysis plan structured data plan enable to true. Currently, it is set to false, that's why your structured data output is empty.

Hey Shubham, how can I do that in the dashboard? I'm having the same issue. My structured data was working fine 2 weeks ago but now it's passing empty values every time. For example, call id - 4359aff3-88bd-4150-a4cd-ca9d75d4911d Usually it would have passed something like this: Date - tomorrow Time - 2 pm Address - 607 Northeast third Place, 79031 Phone Number - 8063151217 But now it's all just empty (image attached). https://cdn.discordapp.com/attachments/1379825752111059175/1380588521932324995/Screenshot_2025-06-06_at_1.43.10_PM.png?ex=68446cc1&is=68431b41&hm=a226575c302dcd178582767f0220d914fe9a1859ca4d0e82dca02f612c322de1& https://cdn.discordapp.com/attachments/1379825752111059175/1380588522171269130/Screenshot_2025-06-06_at_1.43.49_PM.png?ex=68446cc1&is=68431b41&hm=bc2c9b1b81223053fc93ff4f79c8bab75a9ffe6c5ad552f4e19441207f44d469&
