Directus's webhook trigger flows can leak sensitive data

### Describe the Bug In Directus, when a **Flow** with the "_Webhook_" trigger and the "_Data of Last Operation_" response body encounters a ValidationError thrown by a failed condition operation, the API response includes sensitive data. This includes environmental variables, sensitive API keys, user accountability information, and operational data. This issue poses a significant security risk, as any unintended exposure of this data could lead to potential misuse.    ### To Reproduce **Steps to Reproduce:** 1. Create a Flow in Directus with: - Trigger: Webhook - Response Body: Data of Last Operation 2. Add a condition that is likely to fail. 3. Trigger the Flow with any input data that will fail the condition. 4. Observe the API response, which includes sensitive information like: - Environmental variables (`$env`) - Authorization headers - User details under `$accountability` - Previous operational data. **Expected Behavior:** In the event of a ValidationError, the API response should only contain relevant error messages and details, avoiding the exposure of sensitive data. **Actual Behavior:** The API response includes sensitive information such as: - Environment keys (`FLOWS_ENV_ALLOW_LIST`) - User accountability (`role`, `user`, etc.) - Operational logs (`current_payments`, `$last`), which might contain private details.
