Incorrect Logging Level for JSON Format Errors in POST Requests

## Description:

When sending a POST request with an incorrectly formatted JSON body (e.g., containing only the character '}'), the error details are logged with a Level = Debug. This logging level seems inappropriate for this type of error, and it should be logged with Level = Error instead.

Steps to Reproduce:

1. Send a POST request to the API endpoint with a malformed JSON body. For example:
`
}
`
Observe the logs generated by the application.

## Expected Behavior:

The application should log the details of the error with a logging level of Error.

## Actual Behavior:

The error details are logged with a logging level of Debug.

## Environment:

ASP.NET Core Version: 8.0
Operating System: Windows 11

## Additional Information:

Logging critical errors such as malformed JSON requests at a Debug level can obscure important issues that should be promptly addressed. Adjusting the logging level to Error will ensure these issues are more visible to developers and system administrators.
