Htttpcontext and claim not accessible in TenantInfoMiddleware - asp.net-core

Question

I have a employee controller I have added two lines to get the employee TenantName one using httpcontext and a other using user claim. I want to get the TenantName in TenantInfoMiddleware
[HttpPost, Route("login")]
[AllowAnonymous]
public async Task<IActionResult> Login([FromBody] LoginModel user)
{
Claim tenantName = new Claim("TenantName", "erp_colombia");
HttpContext.Items["TenantName"] = "erp_colombia";
}
However in my TenantInfoMiddleware both testHttpContext and testFromClaim are null why is that?
public class TenantInfoMiddleware
{
private readonly RequestDelegate _next;
public TenantInfoMiddleware(RequestDelegate next)
{
_next = next;
}
public async Task InvokeAsync(HttpContext context)
{
List<Claim> claims = new List<Claim>();
claims = context.User.Claims.ToList();
var testHttpContext = context.Items["TenantName"];
Claim claim = claims.Where(x => x.Type == "TenantName").FirstOrDefault();
var testFromClaim = claim.Value;
// Call the next delegate/middleware in the pipeline
await _next(context);
}
}
I have added the TenantInfoMiddleware in startup
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
[Obsolete]
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseMiddleware<TenantInfoMiddleware>();
app.UseHttpsRedirection();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
}
}
