hi

It seems that the connection string is not getting correctly.

You can debug the connectionStringResolver try to get the connection string.

var connectionStringResolver = ServiceProvider.GetRequiredService<IConnectionStringResolver>();

Hi,

I checked the value of connectionStringResolver and this is what I got:

Exception occurs on await _identityServerDataSeeder.SeedAsync(); I already added the [ConnectionStringName(IdentityServiceDbProperties.ConnectionStringName)] attribute to IdentityServiceMongoDbContext

Add MyMultiTenantConnectionStringResolver to your CMVPoint.IdentityService.MongoDB project, I will fix this in 5.3 patch version.

using System;
using System.Threading.Tasks;
using Microsoft.Extensions.Options;
using Volo.Abp.Data;
using Volo.Abp.DependencyInjection;
using Volo.Abp.MultiTenancy;

namespace CMVPoint.IdentityService.MongoDb;

[Dependency(ReplaceServices = true)]
public class MyMultiTenantConnectionStringResolver : MultiTenantConnectionStringResolver
{
    public MyMultiTenantConnectionStringResolver(
        IOptionsMonitor<AbpDbConnectionOptions> options,
        ICurrentTenant currentTenant,
        IServiceProvider serviceProvider)
        : base(options, currentTenant, serviceProvider)
    {
    }

    public override Task<string> ResolveAsync(string connectionStringName = null)
    {
        if (connectionStringName == "Volo.Abp.Identity.MongoDB.IdentityProMongoDbContext")
        {
            return base.ResolveAsync("AbpIdentity");
        }
        return base.ResolveAsync(connectionStringName);
    }

    public override string Resolve(string connectionStringName = null)
    {
        if (connectionStringName == "Volo.Abp.Identity.MongoDB.IdentityProMongoDbContext")
        {
            return base.Resolve("AbpIdentity");
        }

        return base.Resolve(connectionStringName);
    }
}
