OpenIdConnectProtocolException when I have changed primary key in EntityFramework Core

[maihuuthai]

IdentityServer version

4

.NET version

.NET 6

Description

All things work well before.
When I received a request to change the Primary Key column from one field to another in the table, I made the change using an Entity Framework Core command. However, the problem occurred when I restarted my project

Reproduction steps

Model previously

[MaxLength(200)] public string UserId {get;set;} //this is primary key ....... other fields here

DbContext previously
protected override void OnModelCreating(ModelBuilder builder) { base.OnModelCreating(builder); builder.Entity<entity_name_here>(x => { x.HasKey(y => y.UserId }); }

And then somethings have been changed
Model
[DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int Id {get;set;} [MaxLength(200)] public string UserId {get;set;} //this is primary key ....... other fields here

DbContext
protected override void OnModelCreating(ModelBuilder builder) { base.OnModelCreating(builder); builder.Entity<entity_name_here>(x => { x.HasKey(y => y.Id }); }

===== Command dotnet ef migrations add .... has been used ===== successfully, database has been changed.
But, when I started the project that throws an exception as below

Expected behavior

Not throw exceptions.

Unfortunately IdentityServer 4 is out of support. It has a lot of security vulnerabilities that will not be fixed. We recommend to upgrade to Duende IdentityServer 7 as soon as possible.

Having said that: it's not possible to change the DbContext like that without changing the code that uses it. You'll have to dig into the code that uses this entity and modify/override it to make it work with the new model.

Yes, I see. I just made a change to an existing model, but I don't understand why it's throwing an exception in OpenID Connect after logging in. I don't see how it's relevant either
