how to have http response with pipe throwing error?
原标题:

I have a nestjs application in which I created a pipe to check if value is a valid URL. If the URL is invalid, throw error. This is used in a controller to save an item into the database.

I just realized the pipe would just throw 500 with Internal Server Error, I had to check the server log to see if it s actually from the pipe.

I wonder if there s a way that we can have http response directly with the message?

The pipe code I have is...

import { BadRequestException, Injectable, PipeTransform } from  @nestjs/common ;

@Injectable()
export class ValidUrlPipe implements PipeTransform {
  transform(website: string) {
    if (website ===   ) return website;

    const validProtocols = [ http: ,  https: ];

    const { protocol } = new URL(website);
    if (validProtocols.includes(protocol)) {
      return website;
    }

    throw new BadRequestException(`invalid website value: ${website}`);
  }
}

the controller using the pipe looks like

  @Post()
  create(
    @Body( website , ValidUrlPipe) website: string,
    @Body() createTvDto: CreateTvDto,
    @CurrentUser() user: User,
  ) {
    return this.televisionsService.create(user._id, createTvDto);
  }

Thank you so much in advance for any suggestions/solutions.
