error while Embedding paginated report with parameter using power bi client angular

[appsac1]

I am trying to Embed a paginated report in my web application using power bi client angular .
Till now i am successfull to embed the paginated report with single parameter sent with url.
The parameter i am sending with url is getting added dynamically in url (user select an option from dropdown which i am binding as paramter).
My solution is working fine for the first load but when i try to change any parameter from drop down , the report throwing below error. 

And this is how my parameterized url looks like: 
https://app.powerbi.com/rdlEmbed?reportId=XXX&config=XXX&rp:PropertyName=The Plaza&rp:PropertyName=The Taft

The same URL works on the first load but it doesn't work if i change any parameter and try to load the report.
To embed the report i am using powerbi-client-angular library.
https://www.npmjs.com/package/powerbi-client-angular 
Please help me with the issue or let me know if more details required.
