API File Search

API File Search

What am I doing wrong  (Zoho creator using WorkDrive API)?:

void API.FileSearch()
{
TeamID="n8gep5faacf7a854a4a5f83d1b75xxxxxxxx"
Token = thisapp.API.GetAccessToken();
TokenText = "Zoho-oauthtoken " + Token;
headerMap = Map();
headerMap.put("Accept","application/vnd.api+json");
headerMap.put("Authorization",TokenText);

urlstring = "https://workdrive.zoho.com/api/v1/teams/"+TeamID+"/records?search%5Ball%5D=590582.pdf";
resp = invokeurl
[
url :urlstring
type :GET
headers:headerMap
detailed:true
connection:"workdrive"
];
info resp;
}

result:
