Description

Develop an endpoint to allow users to update their comments on a blog post. The endpoint should validate that the comment exists, that the user owns the comment, and then update the content while preserving the original creation date. The response should return appropriate status codes based on different validation scenarios.

Requirements

• Method: PUT
• URL: /api/v1/posts/{blogId}/comments/{commentId}
• Headers: Content-Type: application/json

{
  "message": "Comment updated successfully.",
  "success": true,
  "data": {
