Answer
Check for the following:
Search Your Codebase
Use your IDE’s "Find in Files" feature to search for:MaxLength(250) StringLength(250)
"First Name must be less than 250 characters"
If your frontend (e.g., Angular, React) has validation rules, it could send invalid data to the API. Check client-side validation logic.
Locating EF Fluent API Configuration If you’re using Entity Framework’s Fluent API, check your DbContext class:
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<User>()
.Property(u => u.FirstName)
.HasMaxLength(250);
}
