Flow Action - Convert Word Document to PDF

Hello everyone, 
I am trying to convert word into PDF using the same action but when I try to pass dynamic value in "Document Library" parameter, I am getting error.

{

  "status": 404,

  "message": "The selected file doesn't exist, please select a valid file and drive.\r\nclientRequestId: 7c6b5a78-ff64-4156-b95c-19aa5423a60b",

  "error": {

    "message": "The selected file doesn't exist, please select a valid file and drive."

  },

  "source": "wordonlinebusiness-scus.azconn-scus-001.p.azurewebsites.net"

}

But when I chose it from dropdown, everything goes well.

My requirement is to choose document library dynamically because we create new libraries through Power Automate.

Please let me know how can I convert word into PDF by passing dynamic value into Document Library parameter or is there any alternate solution?
Thanks
