In am trying to encrypt each request with the help of this code:

encryptRequest(request) {
let encryptInfo = encodeURIComponent(CryptoJS.AES.encrypt(JSON.stringify(request), ‘The screat key’).toString());
return encryptInfo;
}

and calling this code while sending request in service file. Like:

public checkAccess(solutionName: string = ‘Business Card Management’) {
let encryptReq = {
solutionName
}
let req = this.encryptDecrypt.encryptRequest(encryptReq);
return this.httpClient.post(${this.envConfigService.serverHost}/${ApiEndpointsEnum.CHECK_ACCESS}, req)
}

And then I have add decryption code in node js, in one called decryption.ts:

function decryption(req) {
var deData= CryptoJS.AES.decrypt(decodeURIComponent(req).toString(), ‘The screat key’);
let decryptedInfo = deData.toString(CryptoJS.enc.utf8);
return decryptedInfo;
}

And calling this in route like:

this.router.post(this.checkUserAccess, decryption, this.cardsController.checkUserAccess);

Getting encrypted data like this, shown in image.

But not getting decryption code it is coming undefined like shown in image.
