How to cp file only if it does not exist, throw error otherwise?

help you fix your problem You could test for the existence of a file by listing the file, and seeing whether it returns something. For example:
aws s3 ls s3://bucket/file.txt | wc -l
aws s3 sync . s3://bucket/ --exclude '*' --include 'file.txt'

Django: Check if user input does not exist in db and throw ValidationError

Hope that helps Since you need a custom validator(as you mentioned in comments), you can create a validate_id_exists validator for your id field.
validate_id_exists validator checks if an Incident object exists with the given id. If it does not exists, it raises a ValidationError.
from django.core.exceptions import ValidationError

def validate_id_exists(value):
    incident = Incident.objects.filter(id=value)
    if not incident: # check if any object exists
        raise ValidationError('This does not exist.') 
class IncidentSearchForm(forms.Form):
    id = forms.IntegerField(label="ID", required=False, validators=[validate_id_exists]) # specify your 'id' validator here

Should my method throw its own exception, or let .NET throw if a file doesn't exist?

it should still fix some issue if (File.Exists(f)) { DoSomething(f) } (or the negation thereof) is an anti-pattern. The file can be deleted or created in between those two statements, so it makes little sense to check its existence like that.
Apart from that, as pointed out in the comments, while File.Exists() may return true, the actual opening of the file can then still fail for a variety of reasons. So you'll have to repeat the error checking and throwing around the opening of the file.

I hope this helps . If you create a document using the routing parameter, which seems to be your case according to the sample document you're showing, then you also need to specify the routing parameter ?routing=15375 when deleting your document.

How to throw exception using nest js if user exist on mongo and else create the user?

wish helps you You can modify your user.service.ts file so that it might contain a separate method to check if the user exists.
async doesUserExists(createUserDTO: CreateUserDTO): any {
    const user = await this.userModel.findOne({ userName: createUserDTO.userName });
    if(user.length != 0){
        return true;
    return false;
// add a user
async addUser(@Res() res, @Body() createUserDTO: CreateUserDTO) {
    if(await this.userService.doesUserExists()){
        return res.status(HttpStatus.OK).json({
            message: "User already exists"
    const user = await this.usersService.addUser(createUserDTO);
    return res.status(HttpStatus.OK).json({
        message: "User has been created successfully",
