Handle errors and limits

Every error has a code and a message written for your users.

errors.js

try {
  const reply = await charge.ai.chat(text)
  out.textContent = reply.text
} catch (e) {
  if (e.code === 'cancelled') return          // the user closed a sheet
  out.textContent = e.message                  // already written for the user
}

cancelled: the user closed the sign-in or payment sheet. Do nothing.
daily_cap: your app reached the daily limit this user set. ChargeMyAI already offered them their account.
paused: the user paused spending in all apps.
popup_blocked: the browser or a preview frame blocked the sign-in window.
device_unavailable: you asked for mode: 'device' and the device can't answer.
upstream_unavailable: no model answered. The user was not charged.
