Error in connecting to WorkDrive

I'm trying to write a script to look in a specific WorkDrive folder and if there is a csv or xslx file, copy it to a different folder with a modified filename. That gave me the error: {"errors":[{"id":"F6016","title":"URL Rule is not configured"}]}

So I stripped the function down to the code below to test the connection, but still get the same error. I checked the connection scopes and all looks good, but I can't see an option to configure a URL Rule. What am I missing?

string standalone.copy_file()

{

response = invokeUrl

[

url: "https://workdrive.zoho.com/api/v1/folders/[MyFolderId]/files"

type: GET

connection: "workdrive_connection"

];

info response.toString();

return "";

}
