Select iteration path for printing: selection of iteration works intermittently

[primaju]

Describe the bug
Regardless which iteration path for printing is selected. Page footer returns "Printing selected work item types in @currentiteration with 0 work items." and popup appears with the text "No work items were returned, please check the options selected and that work items are assigend to the iteration". Although after some time it works for a single selection and then stops again.

Azure DevOps Server 2019.1

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Sprints'
2. Click on 'Print'
3. Message with no items popup
4. Select different iteration
5. Same message with the same footer appears disregarding selection of iteration

Expected behavior
It is expected to return items and the footer below should not show "Printing selected work item types in @currentiteration with 0 work items.", the selected iteration is not represented

Screenshots
There is no way to present a screenshot

Desktop (please complete the following information):

• OS: Windows 10
• Browser:
  Chrome 77,
  Microsoft Edge 41.16299.1004.0,
  Microsoft Edge 79.0.294.1

Additional context
It seems that the query is stuck or cached and selection of the iteration is not preserved during the postback.
After some investigation it looks like the dataService.setValue for userIterationPath is set but lost after reload
let iteration = dataService.getValue("userIterationPath", {scopeType: "User"}); is not getting the value.

@primaju thank you for the issue report - are you able to post the content of the browser console when this happens. I'll take a look at the code getting the data.

board-cards.html:867 83: triggerPrint()

after looking to the code of the solution board-cards.html source I could see that code
dataService.setValue('userAreaPath', linkId, {scopeType: 'User'}).
is never waited to execute because reload is hit before and page does not wait for value to be set.

I would suggest adding extra then block and add location.reload(true); there, or
update onclick funtion to async and add await for VSS.getService
