Step 2: User Profile Investigation

console.log(`\n=== User Investigation: ${userId} ===\n`);
// Test if we can identify (update) the user — confirms they exist
try {
await cio.identify(userId, {

});
console.log("Profile: EXISTS (identify succeeded)");
} catch (err: any) {
console.log(`Profile: ERROR (${err.statusCode}: ${err.message})`);

// Test if we can track an event on the user
try {

data: { checked_at: new Date().toISOString() },
});
console.log("Event tracking: WORKING");
} catch (err: any) {

// Check suppression status by trying to unsuppress
// (If user is not suppressed, this is a no-op)
