await challege.getImage() not working.
I check your source. challenge.js

async getImage(): Promise<Buffer> {
        let img = await this.imgs[this.wave];
        try {
            JSON.parse(img.toString()); // Image is encrypted
            img = Buffer.from(
                await crypt.decrypt(img.toString(), await this.getKey()),
                "base64"
            );
        } catch (err) {
            // Image is not encrypted
            // All good!
        }
        return img;
    }

console.log catch error => ACCESS DENIED
