Update Polar SDK checkout API for v0.42.5 compatibility

[Copilot]

The Polar SDK API changed between v0.20.2 and v0.42.5, breaking the checkout flow. The checkouts.custom.create() method no longer exists.

Changes

• Updated checkout API call from polar.checkouts.custom.create() to polar.checkouts.create()
• Changed parameter structure: productPriceId now passed as products: [productPriceId] array per new API requirements

// Before
result = await polar.checkouts.custom.create({
  productPriceId,
  successUrl: 'https://docs.shepherdjs.dev'
});

// After
result = await polar.checkouts.create({
  products: [productPriceId],
  successUrl: 'https://docs.shepherdjs.dev'
});

The new API requires products as an array of product IDs. The SDK was completely regenerated in v0.6.0, eliminating the custom namespace.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• docs.polar.sh
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)
• download.cypress.io
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node index.js --exec install (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
