EF migration in VScode

I tried to do a migration with dotnet ef migrations add InitialCreate and I obtained the message : Build started... Build succeeded. System.ArgumentNullException: Value cannot be null. (Parameter 'connectionString')

appsettings.json

"ConnectionsStrings":{ "DefaultConnection":"Data Source=(localdb)\LocalDBApp1;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False;ApplicationIntent=ReadWrite;MultiSubnetFailover=False" },

Startup.cs

services.AddDbContext(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

Have you an idea how I can solve this problem? Thanks in advance

Probably a typo, try with ConnectionStrings instead of ConnectionsStrings in your appsettings.json.
