I am new to Appian-Locust and require some assistance in order to create the test script for Performance testing.

from appian_locust import AppianTaskSequence, AppianTaskSet
from locust import task, HttpUser


class Maestro(AppianTaskSet):

    @task
    def homePage(self):
        response = self.client.get('/suite/sites/telus-tools')
        if response.ok:
            pass
        else:
            print('Application link not found')


        DesignUiForm = self.appian.visitor.visit_application_by_name('Maestro Workflow Management')
    #     DesignUiForm = self.appian.visitor.visit_application_by_id(1)
    #     DesignUiForm.click('Telus Workflow Management')
       

    # self.appian.visitor.visit_record_type('Activity')
    #   self.appian.visitor.visit_report('TWM_activityRecordList',True)
    #  self.appian.visitor.visit_application_by_name('Telus Workflow Management','TWM')


class MyUser(HttpUser):
    tasks = [Maestro]
    host = 'https://xxxxx.appiancloud.com'
    auth = ["username", "password"]

    def __init__(self, environment) -> None:
        super().__init__(environment)
        self.client.record_mode = True

I am getting below error when trying to run this code:

Error report
# occurrences Error
------------------|-------------------------------------------------------------------------------------------------------------------------------------------
3 GET Design.ApplicationList: HTTPError('500 Server Error: 500 for uri: /suite/rest/a/applications/latest/app/design Username: username')
------------------|-------------------------------------------------------------------------------------------------------------------------------------------


It would be most appreciated if some help me in resolving this issue as early as possible.

Thanks,
Shafi
