Passing the parameter at run time from the URL

I am creating a BIP report and want to pass parameters from the URL. For example, I have a report with a parameter for Assignment ID. When I open the report, it should look for the Assignment ID in the URL and run the report. Here is an example of the URL. It used to work on Responsive pages but is not working on Redwood pages. Any suggestions?

example url:
https://hcm_domain/xmlpserver/Custom/Human%20Capital%20Management/Checklist/Job%20Competencies.xdo?_xpt=1&_paramspAssignmentId=#{pAssignmentId}
