Issue when suitelet page redirects to Netsuite Login

Issue

The suitelet page will redirect to netsuite login page when open by clicking on suitelet URL

Solution

The suitelet page will open without redirecting to Netsuite Login page when the returnExternalUrl is set to true while calling the suitelet script from any other scripts. Following is the code snippet to set it true.

var output = url.resolveScript({
    scriptId: 'custom_script',
    deploymentId: 'custom_script_deployment',
    returnExternalUrl: true
});
