callback-missing-request-body-with-mapping

Overview

This rule belongs to the apimatic-codegen-validation ruleset and states that:

This callback is assigned to a callback group that has discriminator mappings, but the callback itself doesn't have a request body parameter. Since discriminator functionality relies on request body content for event type determination, the callback can't be removed without breaking the discriminator mappings.

Suggested Fixes

• Add a request body parameter to the callback definition.
• Ensure the request body parameter has ParamFormat.Body format.
• Define an appropriate schema for the request body that contains the discriminator field.
• If the callback doesn't need a request body, remove it from the group or remove the discriminator mappings that reference it.
