presignedUrl generate XML file with error instead of generating error in callback

[LucBrungard]

Hello everyone, I'm working on a NestJS API using Express structure. I'm trying to generate a link from an object in a bucket with the function presignedGetObject. I intentionally put a wrong objectName to see if i handled the error like I wanted but it occurs that the function send back an url containing a XML file with the error I should get in my callback : NoSuchKey

<Error>
    <Code>NoSuchKey</Code>
    <Message>The specified key does not exist.</Message>
    <Key>query.filePath</Key>
    <BucketName>luc</BucketName>
    <Resource>/luc/query.filePath</Resource>
    <RequestId>16F3E13DB9BBF1D0</RequestId>
    <HostId>e08141ca-1f55-4dda-b71c-abd9251ef3c3</HostId>
</Error>

Here is the code I use to get this error : The service containing the functions for my controllers (route handlers)

  generateDownloadLink(bucketName: string, filePath: string): Promise<string> {
    if (process.env.NODE_ENV === 'development') this.logger.debug('Method generateDownloadLink called');
    return new Promise((resolve, reject) => {
      this.minioClient.presignedGetObject(
        bucketName,
        filePath,
        60,
        { 'response-content-disposition': 'attachment;' },
        (error, result) => {
          if (error) reject(error);
          resolve(result);
        },
      );
    });
  }

The route handler (controller) :

  @Get()
  async download(@Req() request: Request, @Res() response: Response) {
    const query = request.query as { filePath: string };

    const responseMessage: ResponseMessage = {
      statusCode: HttpStatus.CREATED,
      timestamp: new Date().toISOString(),
      path: request.url,
    };

    try {
      const link = await this.minioClientService.generateDownloadLink(
        request.user.bucketName,
        'query.filePath',
      );
      responseMessage.message = link;
    } catch (error) {
      responseMessage.message = 'Une erreur est survenue lors de la récupération des données';
      responseMessage.statusCode = HttpStatus.NOT_FOUND;
      responseMessage.error = error.message;
    }

    response.json(responseMessage);
  }

My server app is running on localhost:3000 Using postman to make a GET request i obtain : https://gyazo.com/13eaa6dcee43e27bbaacd0564770701d When I click on the link in the message field, it gives me the content I put at the beginning of this message

I saw only 1 issue related to my case : https://github.com/aws/aws-sdk-js/issues/1893 I don't know if i misunderstood something in the function or if I use it wrong but I thought that if an error occurred, the error param wold have a value.

still waiting ...

this would be a responsibility of client application. as the sdk could only generate the url. and the url is requested by the http client which needs to handle this.
