Expected Behavior

Get request to /prometheus endpoint:

Steps To Reproduce

1. Start application

2. Send a POST request via postman, with body as application/json:
   { "title": "Example", "length": 123 }

3. Get the response: 500 Internal Server Error, with body:
   { "message": "Internal Server Error", "_links": { "self": { "href": "/", "templated": false } }, "_embedded": { "errors": [ { "message": "Internal Server Error: class java.lang.Long cannot be cast to class java.lang.String (java.lang.Long and java.lang.String are in module java.base of loader 'bootstrap')" } ] } }
   Printed into the console:
   ERROR i.m.http.server.RouteExecutor - Unexpected error occurred: class java.lang.Long cannot be cast to class java.lang.String (java.lang.Long and java.lang.String are in module java.base of loader 'bootstrap') java.lang.ClassCastException: class java.lang.Long cannot be cast to class java.lang.String (java.lang.Long and java.lang.String are in module java.base of loader 'bootstrap') at

4. Send a POST request via postman, with body as application/json:
   { "titles": "Example", "length": 123 }

5. Get the response: 400 Bad Request, with body:
   { "message": "Bad Request", "_links": { "self": { "href": "/", "templated": false } }, "_embedded": { "errors": [ { "message": "Failed to convert argument [body] for value [null] due to: Instantiation of [simple type, class com.example.dto.BodyDto] value failed for JSON property title due to missing (therefore NULL) value for creator parameter title which is a non-nullable type\n at [Source: UNKNOWN; byte offset: #UNKNOWN] (through reference chain: com.example.dto.BodyDto[\"title\"])", "path": "/body" } ] } }
