I am working on Zapier App using zapier UI, for which I require dynamic drop-down for one of my trigger,

I have tried many things still getting errors, finally I have also tried to add static response for drop-down, still getting same error,

let custom_result = {};
custom_result['status'] = '1';
custom_result['data'] = ["8453930101","8453930112","8453930103","8042073178"];
custom_result['id'] = 1;

return [custom_result];

Please check these screenshots and help me out,
