Power BI embed in Jupyter notebook methods from report class won't work inside interact callback

Hi experts,

I'm facing a weird behaviour in powerbiclient embeded in Jupyter notebook.

Have embedded the report using the following code

from powerbiclient.authentication import MasterUserAuthentication
from powerbiclient import Report,models
#authenticate
auth_token = MasterUserAuthentication(username="[email protected]", password="xxxx")
#embed the report

global report
report = Report(group_id="xxxxxxxx", report_id="xxxxxxxx", auth=auth_token)
report

Embedding works fine

After this I want to perform some programatic extract from the embedded report like below 

page_list = ['ReportSectiond8ab5d035cceb8586528','ReportSection1dea67c2520bce38f54f','ReportSection4b3fbaa7dd7908d906d9']
def print_visuals(ReportPage):
    print(report.visuals_on_page(ReportPage))

interact(print_visuals, ReportPage=page_list)

This would work for the first time, meaning the above code will display a dropdown, if i select a page name from the dropdown it will print the visuals of that page. But second time if I change the value in the dropdown it won't work. It won't throw any error messages. But after this behaviour, no code will run in the jupyter nook page, I have to restart the kernal.

I tried the same thing using observe event on the dropdown widget, but the same behaviour.

If I do some other operation inside the interact/observe callback function other than invoking methods from powerbiclient's report class, it will perfectly work.

Please help.
