Chapter 2: User Management - Cant validate code

Hi,
I see the error (in the screenshot) when I try to validate my code for the User Management ticket. Everything else seems to work fine but just this one keeps failing

Same error.

On http://localhost:5000/status, while validating
User Management: invalid response to register

@ameyaraje, is this the full stacktrace?

@rtikoo all unit tests are passing ?

N.

There’s quite a bit more, but those seem to be pointing to the Spring packages. This was the only section pointing to the mflix part
I’m able to pass all unit tests, and I can still validate all previous tickets!

The corresponding unit test is passing
$ mvn test -Dtest=UserTest

I had the same issue. Solution is to rebuild with jdk1.8.0_65.

@Andrews_54551 Thanks for the suggestion. maven was pointing to Java 11 on my machine which was causing this issue. Now, maven is pointing to Java 8.

mflix rtikoo$ java -version
openjdk version “1.8.0_121”
OpenJDK Runtime Environment (Zulu 8.20.0.5-macosx) (build 1.8.0_121-b15)

However, I am still not able to validate the ticket inspite of the UserTest tests passing.
I get a invalid response to login message. No errors in the Spring console.

says
Now proceed to the status page to run the full suite of integration tests and get your validation code.
I am assuming this refers to just the User Management test and the ones before it (since they should have been passing because of the previous lessons)?

I havent been able to solve this despite the java version

@ameyaraje
Can you paste the output of java -version and mvn --version?

@rtikoo review your implementation of the UserDao.createUserSession.
The other issue that might be ocuring is related with some dirty data, resulting of the previous JDK 11 runs.
This can be fix by cleaning up the sessions collection in your cluster.

To do this, connect to your Atlas cluster via mongo shell and run this command:

db.sessions.drop()

Let me know if this fixes the issue.

Came back to this version. Tried going back to the version @Andrews_54551 said on a different VM

Hi Noberto,

I am also facing similar issue while validating user Management Ticket. Test passes without any failure but I get “User Management: invalid response to login”. I don’t see any error in the spring console.

My java and maven version are java 8

Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T10:41:47-06:00)
Maven home: C:\apache-maven-3.3.9\bin…
Java version: 1.8.0_201, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk1.8.0_201\jre

I even tried removing all the sessions. any help is appreciated.

Thanks
H

Thanks @Norberto

  1. Dropping the sessions helped.
  2. In addition, there was an issue where the createUserSession was returning false when it was modifying an existing user session instead of creating a new one. Changing it to return true in both cases (insert and update) led to a different message on the status page.

“duplicate-emails-should-not-be-allowed”

  1. I searched the discussion forums and read
    User Management: duplicate emails should not be allowed [Solved]

Had to fix my addUser implementation to return false if the user email already exists.

For point 2 (above), I am still not sure if it should return true for both inserts and updates but it seems to make the validation pass.

Hi @rtikoo,

Is there away that you could both operations using only one command?
Essentially, this is an updated or an insert, if the document does not exist. I’m pretty sure there is something we can do in one single command :wink:

If you still want to use two commands, both should

  /**
   * Creates session using userId and jwt token.
   *
   * @param userId - user string identifier
   * @param jwt - jwt string token
   * @return true if successful
   */
  public boolean createUserSession(String userId, String jwt) {

return true

if successful !

N.

@dhprasad77 check your createUserSession again. The unit test is not capturing the creation of multiple user sessions.
We will fix that, but in the meantime make sure that in case the user is already logged in, the session jwt will get updated.

N.

Same issue. I solved it with try catch case.

try {
....
return true;
} catch (MongoException ex) {
return false;
}

All test cases passes, but not getting the validation code. Not sure what’s wrong.
On checking network tab it looks like it’s failing on addUser().
try {
usersCollection.insertOne(user);
} catch (Exception ex)
{
throw new IncorrectDaoOperation(ex.getMessage());
}
return true;

Not sure what needs to be done here or what’s wrong here.

Please share any error messages you get.

I have debugged code, I see addUSer method getting called twice and again if user exist I am already throwing the exception as expected in method signature. This is tripping me in what wrong I am doing ,

Hi @tapanggupta,

Please share the console error messages that you see in the console when you run the status page.
