I am working on a Server/Client Blazor app using Interactive Web Assembly. I have a page that lists some objects (Tenants), and when clicking on those objects, it navigates to a page with the ID of the object as a parameter in the Uri path.

/tenants/ -> /tenants/{Id}

When navigating via clicking on the link, everything works properly and I have no issues. However, if I directly enter the Uri to the specific object in the browser, I get a generic NullReferenceException which appears to be generating from my Server’s DbContext.OnConfiguring() method based on going through breakpoints, but on the “no code to show” page. Below are the relevant code snippets (some code removed for brevity). I feel like this is a lack of knowledge on my part with respect to Interactive Web Assembly as it just doesn’t make sense to me otherwise. Any help would be appreciated.

Single Tenant Page (Client)

@page "/tenants/{Id}"
@inject HttpClient httpClient

@code {
  [Parameter]
  public string Id { get; set; } = null!;

  TenantClientService tenantService = null!;

  protected override async Task OnInitializedAsync() {
      tenantService = new TenantClientService(httpClient);
      targetTenant = await tenantService.GetTenantAsync(Guid.Parse(Id)) ?? throw new InvalidOperationException($"Tenant with ID {Id} not found"); // <--- Throwing here
  }
}

tenantService (Client)

internal async Task<Tenant?> GetTenantAsync(Guid id) {
    Logger.LogInformation("Getting tenant with id {id}", id);
    Tenant? tenant = await HttpClient.GetFromJsonAsync<Tenant>($"{_endpoint}/{id}"); // <--- Throwing here
    if(tenant is null) {
        Logger.LogError("Failed to get tenant with id {id}", id);
    }
    return tenant;
}

Controller (Server)

[HttpGet("{id}")]
public async Task<IActionResult> Get(Guid id) {
    Tenant? tenant = await tenantRepository.GetTenantByIdAsync(id); // <--- Throwing here
    if (tenant is null) {
        return NotFound();
    }
    return Ok(tenant);
}

Repo (Server)

public async Task<Tenant> GetTenantByIdAsync(Guid id) {
    Logger.LogInformation("Getting tenant with id {id}", id);
    Tenant? tenant = await Context.Tenants.FindAsync(id); // <--- Throwing here
    if (tenant is null) {
        Logger.LogError("Tenant with id {id} not found", id);
        throw new ArgumentNullException(nameof(id), "Tenant not found");
    }
    return tenant;
}

DbContext (Server)

protected override void OnConfiguring(DbContextOptionsBuilder options) {
    options.UseNpgsql(  // <--- Seems to be throwing somewhere here.
            new NpgsqlConnectionStringBuilder {
                Host = config.Host,
                Port = config.Port,
                Database = config.Database,
                Username = config.Username,
                Password = config.Password
            }.ConnectionString
        )
}

I tried navigating to the page via direct URL (i.e. https://localhost:7190/tenants/48277ddd-342e-4a99-b683-cce1c953f564) and expected to get the same result as navigating via the link from the tenant list, but instead got a NullReferenceException.
