Summary

Issue: Enabling strict: true on a prompt’s structured output causes a runtime validation error because the required array is not automatically added to the schema. Cause: Strict mode does not auto-generate required — it must be defined manually for all properties in the schema. Resolution: Add the required array to your schema via the UI or JSON schema editor.

​
Resolution steps

​
Add required property to fields in UI schema editor:

​
Step 1: Open the schema editor

In the prompt editor, open the structured output schema dialog.

​
Step 2: Add required to each property

Use the dropdown next to every property’s type field and select the required option.

​
Step 3: Save the prompt

Click Update to save. Verify the required array is present in the JSON before navigating away.

​
Add required directly in the JSON object:

​
Step 1: Open the schema editor

In the prompt editor, open the structured output schema dialog.

​
Step 2: Select the JSON Schema editor view

Open the schema editor view type dropdown and select JSON

​
Step 3: Update JSON schema

Ensure your schema includes a required array listing all defined properties: 
{
  "type": "object",
  "required": [
    "reasoning",
    "classification"
  ],
  "properties": {
    "reasoning": {
      "type": "string",
      "description": "The reasoning for why the classification judgement was made"
    },
    "classification": {
      "enum": [
        "good",
        "bad"
      ],
      "type": "string",
      "description": "Classification of whether the content is good or bad"
    },
  },
  "additionalProperties": false
}
