How to fix “The CORS protocol does not allow specifying a wildcard (any) origin and credentials at the same time” error

Question

I\'ve already enabled CORS on the project in C# .net Core

In startup.cs I\'ve added lines

...
services.AddCors();
...
app.UseCors(builder =         


        

Answer 1

You cannot use both AllowAnyOrigin() and AllowCredentials() at the sametime so change your code to:

...
services.AddCors();
...
app.UseCors(builder => builder
    .WithOrigins("https://example.com")
    .AllowAnyMethod()
    .AllowAnyHeader()
    .AllowCredentials());
