Project solutions are missing from certified user data

[huyenltnguyen]

Description

Some project solutions are broken / missing from certified user data, and we have an error message next to those projects.

Screenshot

Projects with broken solution are:

• Responsive Web Design
  • Build a Survey Form
  • Build a Tribute Page
  • Build a Technical Documentation Page
  • Build a Product Landing Page
  • Build a Personal Portfolio Webpage
• Relational Database
  • Celestial Bodies Database

We also have some projects which don't have a solution (the solution column is empty, rather than displaying an error message).

@ilenia-magoni Correct me if I'm wrong, but I understand that we have to show an error message in case of no solution.
Is there anything to be done about the broken/missing solution?

[ilenia-magoni]

@Deep512 no, the certified user data has to contain the project solutions

[RavidYael]

Hi @ilenia-magoni,

I've started addressing the issue and have a couple of questions based on your last comment about the certified user data needing to contain project solutions.

1. Critical Question: Are you certain this is only a development environment issue and not present in production? Currently, the code doesn't make the solution field mandatory, and from a quick glance at curriculum.json, I noticed some challenges entirely lack a solution attribute. This raises concerns that this issue could also exist in production. If so, perhaps better error handling, as suggested by @Deep512, might be a good approach.

2. Potential Solution: How do you suggest we approach fixing this issue given that numerous challenges currently lack solutions?

Thanks in advance!

[ilenia-magoni]

this issue is specifically to add the missing data to the mocked user @RavidYael , as such it can't be present in production. The mocked user is missing data as it has not been updated for the latest releases. The only saved solutions are those of final projects, as such we don't care that many challenges lack solutions, those solutions are not saved for each user, so they don't matter for the mocked user.

I am not sure you understand what this issue is about with this question. This is to update the certified-user with which the database can be seeded in the development environment.

[RavidYael]

I understand, in production, we will present the actual solution of the user. Thanks for clarifying!

[ilenia-magoni]

@RavidYael we do not give solutions to users, and this issue is impossible in production because it's about the script that creates a false user data in the development database

[RavidYael]

I'm not sure I fully understand. When a user completes the "Build a Survey Form" project, what would they see in the solution section in production?

@RavidYael There would be a "View" button that opens a link to their completed solution to the challenge. Like below. The user in the development database does not have a proper completed solution, as such it provides an error.

The user in the development database does not have a proper completed solution, as such it provides an error message. Are you with me so far?
