question: @Matches acting weird

Hi there,

I think it is a bug, but I might be doing something wrong.

Description

See the following class:

class Example {
    @Matches(/^[0-9]{2}\/[0-9]{4}$/g)     // MM/YYYY format
    @IsOptional()
    from?: string;

    @Matches(/^[0-9]{2}\/[0-9]{4}$/g)     // MM/YYYY format
    @IsOptional()
    to?: string;
}

When I am only populating either of the fields, it works as expected.

const a = new Example();
a.from = "05/2017";

validate(a);    // gives no error

But when I am populating both fields, it gives me an error:

const a = new Example();
a.from = "05/2017";
a.to = "05/2020";

validate(a); // gives an error

from must match /^[0-9]{2}\\/[0-9]{4}$/g regular expression

There is an extra \ in the error message, it might have something to do with.

Environment

• nodejs: 12
• browser
• framework/library

class-validator version: 0.11.1

If someone could have a look it would be appreciated. Cheers

@vlapo Thanks again for taking a look.

I don’t think either. I don’t need g actually. I never came across this before, so I really appreciate your efforts.
