Package json ^^^

#

import { ExceptionFilter } from 'src/globals/filters/exception.filter';
import { ThrottlerBehindProxyGuard } from 'src/globals/guards/throttler-behind-proxy.guard';
import { UsersModule } from 'src/modules/users/users.module';
import { Module } from '@nestjs/common';
import { APP_FILTER, APP_GUARD } from '@nestjs/core';

@Module({
  imports: [UsersModule],
  providers: [
    {
      provide: APP_GUARD,
      useClass: ThrottlerBehindProxyGuard
    },
    {
      provide: APP_FILTER,
      useClass: ExceptionFilter
    }
  ]
})
export class AppModule {}

#

app.module.ts ^^^

#

#

Structure ^

#

    {
      provide: APP_GUARD,
      useClass: ThrottlerBehindProxyGuard
    },

When I remove this, everything works ^

#

import { RateLimitException } from '../exceptions/impl/rate-limit.exception';
import { Injectable } from '@nestjs/common';
import { ThrottlerGuard } from '@nestjs/throttler';

@Injectable()
export class ThrottlerBehindProxyGuard extends ThrottlerGuard {
  protected getTracker(req: Record<string, any>) {
    return (
      req.headers['cf-connecting-ip'] ??
      req.headers['x-forwarded-for'] ??
      req.ip
    );
  }

  protected throwThrottlingException(): Promise<void> {
    throw new RateLimitException();
  }
}

#
