Nestjs TypeORM BasicEntity not respecting naming convention

I'm trying to use the SnakeNamingConvention in my nest and TypeORM project but am getting a query error when I attempt to use the BaseEntity.#save method on my custom entity. Here are relevant pieces of code:

app.module.ts

import { SnakeNamingStrategy } from 'typeorm-naming-strategies'

@Module({
  imports: [
    ConfigModule.forRoot({ isGlobal: true }),
    TypeOrmModule.forRoot({ namingStrategy: new SnakeNamingStrategy() }),
    GraphQLModule.forRoot({ autoSchemaFile: 'schema.gql' }),
    UserModule,
  ],
})

users.entity.ts

@ObjectType()
@Entity('user')
export class User extends BaseEntity {
  @Field()
  @PrimaryGeneratedColumn('uuid')
  id: string

  @Field()
  @Column({ length: 20, nullable: false })
  firstName: string

  @Field()
  @Column({ length: 25, nullable: false })
  lastName: string
}

users.service.ts

@Injectable()
export class UserService {
  create(createUserInput: CreateUserServiceInput) {
    return User.create(createUserInput).save()
  }
}

My error is:

column "firstName" of relation "user" does not exist
