Current behavior

I have the following code that configures CacheModule with an in-memory or redis store depending on the environment variable configuration.

import { CacheModule } from '@nestjs/cache-manager';
import { Module } from '@nestjs/common';
import { ConfigModule, ConfigService } from '@nestjs/config';
import { redisStore } from 'cache-manager-redis-yet';
import * as path from 'path';
import { ConfigSchema } from './config.schema';
import { validator } from './validator';

@Module({
  imports: [
    CacheModule.registerAsync({
      imports: [
        ConfigModule.forRoot({
          envFilePath: path.resolve(
            process.cwd(),
            `.env.${process.env.NODE_ENV}`,
          ),
          validate: validator(ConfigSchema, (env: Record<string, unknown>) => ({
            driver: env.CACHE_DRIVER,
            url: env.CACHE_REDIS_URL,
          })),
        }),
      ],
      useFactory: async (config: ConfigService<ConfigSchema>) => {
        const driver = config.getOrThrow('driver', { infer: true });
        if (driver === 'in-memory') return {};

        if (driver === 'redis') {
          return await redisStore({
            url: config.getOrThrow('url', { infer: true }),
          });
        }

        throw new Error(`incompatible option for driver: ${driver}`);
      },
      inject: [ConfigService],
    }),
  ],
  exports: [CacheModule],
})
export class CacheInfrastructureModule {}

When driver is redis, I get the following stack trace:

Simplifying the useFactory function to always create redis, I get this error:

      useFactory: async (config: ConfigService<ConfigSchema>) => {
        return await redisStore({
          url: config.getOrThrow('url', { infer: true }),
        });
      },
