Npgsql throws: invalid byte sequence for encoding "UTF8": 0x00

[coderBane]

Description
Npgsql throws an exception because the post request contains binary data.
The data saves to my Postgres database, but because of the exception, I do not get response data.

Steps to reproduce:
Request Model:

public sealed class Dto
{
    [Required]
    public string Name { get; set; }

    [DefaultValue(false)]
    public bool IsActive { get; set; }

    public IFormFile ImageUpload { get; set; }
}

Error:

warn: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[2]
      The response has already started, the error page middleware will not be executed.
fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1]
      An unhandled exception has occurred while executing the request.
