In C# Email Sending - using CKEditor 5 for body of email, OnValidSubmit Email body shows field is empty after entered text ,why?

Created C# Email Sending in Blazor Server App, Before using CKEditor 5 for Email body-Under fluent validation (OnValidSubmit), its working fine but After Using CKEditor 5 for Email Body, body field show empty after entered data.

Entered data in CKEditor 5 Body field, On Validation its showing body is empty, but without Validation for body it works, I expect it to work on Validation
