Custom Middleware https://learn.microsoft.com/en-us/aspnet/core/fundamentals/middleware/write?view=aspnetcore-7.0

Accessing DbContext in Middleware

This error is likely occurring because any middleware acts as a singleton. You have to avoid using member variables in your middleware. Feel free to inject into the Task Invoke, but don't store the inject value into a member object. https://stackoverflow.com/questions/33253834/accessing-dbcontext-in-middleware-in-asp-net-5

public async Task Invoke(HttpContext context, ApplicationDbContext applicationContext) // Method Injection
{
    await _next(context);
}
