Error while copying content to a stream

[EdwinThomas11]

Hello,

I hope you're doing well.

I'm working on implementing a health check in my application. Here are the changes I've made.

Here is the code in the startup.cs

services.AddHealthChecks() .AddSqlServer("MyConnectionString");

services .AddHealthChecksUI(s => { s.AddHealthCheckEndpoint("endpoint1", "https://localhost:5001/health"); }) .AddInMemoryStorage();

app.UseEndpoints(endpoints => { endpoints.MapControllers(); endpoints.MapHealthChecksUI(); endpoints.MapHealthChecks("https://localhost:5001/health", new HealthCheckOptions() { Predicate = _ => true, ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse }); });

Here is the package references:

Here is the json health check:

Here is the health check UI:

I'm not sure why I'm encountering this error ("Unexpected character encountered while parsing value: <. Path '', line 0, position 0.") in the health check UI.

I would appreciate any help you can provide.

Regards, Edwin Thomas

Could you show screenshot from dev tools, network tab? I'm interested in contents of /healthchecks-api request

@dbarwikowski Please find the screenshot for your response

Thanks! Unfortunately it's not helpful :( One more think that might be a problem is https. Is your API setup to use it?

[EdwinThomas11]

@dbarwikowski The issue was due to the authorization for https://localhost:5001/health. After whitelisting this URL, it worked as expected.

I've seen the other issue of yours. Is this still a problem?
