BUG- Error when accessing Jobs for job Selector

[FlorianJacta]

Issue

After the first execution of a scenario, sometimes, no jobs are displayed in the job selector. When submitting the scenario, an error

How to replicate

Run this code, create, and execute a scenario. Retry this same process until the job selector is not working properly.

from taipy import Config

import taipy as tp
import pandas as pd

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

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

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

# 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.Core().run()

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

Expected behavior

Jobs should be correctly displayed in the console, and no error should be thrown.

Environment

Taipy 3.0.0.dev3

@FlorianJacta This should have been fixed. Can you check again?

[FlorianJacta]

@jrobinAV Another issue exists on this one https://github.com/Avaiga/taipy/issues/318. This is a related issue that was fixed by the GUI-Core viz elements but I am not sure on how to test it has been solved in Taipy Core

[jrobinAV]

Fixed!
