    This error means the backend API does not recognize the property securityWebhookBlockIsEnforced in your request payload. Most likely, the UI you’re using is newer than the backend, or a feature flag is enabled in the UI but not yet supported by the backend in your environment.
    What’s happening:
    The UI is sending a property (securityWebhookBlockIsEnforced) that the backend doesn’t expect or support.
    This causes deserialization to fail, resulting in the InvalidRequestContent error.
    How to resolve:
    Check for updates: Make sure both your UI and backend are on compatible versions. If you’re in a preview/early access program, this is a common issue.
    Remove the property: If possible, avoid setting or sending the securityWebhookBlockIsEnforced property until the backend supports it.

    The error occurs because the UI is sending a property (securityWebhookBlockIsEnforced) that the backend API in your environment does not recognize.
     
    This is typically due to a feature rollout mismatch where the UI has been updated but the backend schema has not yet caught up.
     
    The issue cannot be resolved through configuration alone—your best options are to disable the setting if possible, try again later, or raise a support ticket.
     
    In most cases, this resolves once the backend update is fully deployed.
