[zhengAnBin]

Description

Use Class-Validator in DTOs

Minimal code-snippet showcasing the problem

@isNotEmpty({ message: '' })  // ts error
@ApiProperty({ description: '手机号', example: '13222222222', required: true })
phone: number;

Actual behavior

ts: Unable to resolve signature of property decorator when called as an expression. This expression is not callable. Type 'Boolean' has no call signatures.

same problem with me!

Had the same issue and found out after a few hours that it is a typo. isNotEmpty should be IsNotEmpty (capital I)

Mentioned here

thank you

As mentioned by others, the decorators start with a capital letter: @IsNotEmpty. The isNotEmpty is the validator function that is used by the decorator.

Closing this as there is no action to take.
