Syntax to search for folder name within a specified teamfolder

Syntax to search for folder name within a specified teamfolder

This works:
  1. response = invokeurl
  2. [
  3. url :"https://www.zohoapis.com/workdrive/api/v1/teams/" + team_id + "/records?search%5Bname%5D=Acme Ken"
  4. type :GET
  5. headers:header
  6. connection:"workdrive_all"
  7. ];

I need to constrain the search to a specific subfolder. This fails with the ever-mysterious  "Error due to - 'Internal Exception'

What's wrong with my syntax?

  1. response = invokeurl [ url :"
  2. https://www.zohoapis.com/workdrive/api/v1/teams/" + team_id + "/records?search%5Bname%5D=Acme Ken &filter%5BteamFolder%5D=hu1rqa110fb8577d04b088906055a8c088b5b" type :GET headers:header connection:"workdrive_all" ];
  3. type :GET headers:header connection:"workdrive_all" ];
