[🐛 BUG] Status of scenario viewer not updated

[FlorianJacta]

What went wrong? 🤔

I receive that the predictions is ready but the scenario viewer tells me that the scenario is still running.

Expected Behavior

The status should be completed.

Steps to Reproduce Issue

This issue is hard to reproduce. I tried creating some code but failed to reproduce the error. You should be able to reproduce it with this demo https://github.com/Avaiga/demo-covid-dashboard

Run the code, create a scenario, submit it, and observe its status. If the issue is not found, submit it again.

I have tried with 4.0.0.dev0. It may have been fixed in the latest develop version but I cannot install it.

Version of Taipy

4.0.0.dev0

Acceptance Criteria

• [ ] Ensure new code is unit tested, and check code coverage is at least 90%.
• [ ] Create related issue in taipy-doc for documentation and Release Notes.

Code of Conduct

• [X] I have checked the existing issues.
• [ ] I am willing to work on this issue (optional)

This code replicates the issue on my side. This is the develop version of Taipy (8/23/24).

from taipy import Config

import taipy as tp
import pandas as pd

def identity(input):
    print("     Identity")
    return input

Config.configure_job_executions(mode="standalone", max_nb_of_workers=2)

## Input Data Nodes
input_cfg = Config.configure_data_node(id="input_dn", default_data=2)

## Remaining Data Node
output_cfg = Config.configure_data_node(id="output_dn")

# Task config objects
identity_task_cfg = Config.configure_task(
    id="identity", function=identity, input=input_cfg, output=output_cfg, skippable=True
)

# Configure our scenario config.
scenario_cfg = Config.configure_scenario(
    id="my_scenario", task_configs=[identity_task_cfg]
)

scenario = None

page = """
<|{scenario}|scenario_selector|>
<|{scenario}|scenario|>

<|job_selector|>
"""

pages = {"/": "<|navbar|> <|toggle|theme|> <br/>", "Data-Node": page}

if __name__ == "__main__":
    tp.Orchestrator().run()

    tp.Gui(pages=pages).run()

It should be tested again since some related code has been changed.
