Error in CustomValidationPipe

📸 What is this issue?

What is an issue? Please explain with some screenshots.

The parameters using @Query decorator have the type as String in default. We tried to transform the parameters as Number, such like skip or take. However, there is transform: true in CustomValidationPipe, no transform was applied.

After debugging, we found CustomValidationPipe returns the original value after plainToClass and validate processes. The plainToClass makes the original value to be transformed, so the transformed values(parameters) must be returned as transform result.

The code image shows a result that should have changed. In previous, value is returned instead of transformed (object).

✨ Expected Results

What result do you expect?

To use @Transform decorator in DTO, CustomValidationPipe should be changed to return the transformed object. For the moment, transform returns the original value.
