how to resolve this? 

Answer 1

I have resolved the Error.

I made adminjs module wait 5 seconds before initialize:

import { AdminModule as AdminJsModule } from '@adminjs/nestjs';
import { adminModuleOptions } from './admin-module.options';

AdminJsModule.createAdminAsync({
    useFactory: async () => {
      await new Promise((resolve) => setTimeout(resolve, 5000));
      return adminModuleOptions;
    },
  }),

Then i made mongoose module wait 5 seconds before connecting:

MongooseModule.forRootAsync({
    useFactory: async (): Promise<MongooseModuleOptions> => ({
      uri: mongoCredentials.url,
      connectionFactory: () => {
        const connection = mongoose.connection;
        setTimeout(() => mongoose.connect(mongoCredentials.url), 5000);
        return connection;
      },
    }),
  }),
