Looks like filters (parameters) are not applied and not fetched for Paginated Reports similar to Sample Reports as shown in demo (https://microsoft.github.io/PowerBI-JavaScript/demo/v2-demo/index.html#)
report.setFilters([filter]);
report.getFilters();
Is there any way to fetch filters and apply them for embedded Paginated reports?
Power BI embedded JS SDK doesn't support get / set filters on Paginated reports.
In Power BI Embedded Playgroud: go to Sample Tool -> Sample Paginated Report -> hit "Run" on the code section to embed a sample paginated report -> navigate to "Interact" tab to see all the supported APIs for paginated reports
