embedded paginated report with parameters doesnt work

Hi,jostnachs .I am glad to help you.

For your current issue, I think it could be due to slight differences in the values of the fields in the Power BI report and the values of the same named fields in the paged report. For example, there is a formatting difference between the value in the normal report filter field and the value in the paged report. This results in an empty paging report.
I am very concerned about the issue you are experiencing, can you please let me know if you have resolved this ISSUE by now and if you can provide more detailed steps on how to do it, it will help to quickly find out what the problem is.

I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.
Best Regards,
Carson Jian
