Stack trace classification — Shopify

Merchant code (fixable)

Stack frames from these paths point to code the merchant owns and can edit:

cdn.shopify.com/s/files/ — theme assets (JS, CSS, images) served via Shopify CDN
cdn.shopify.com/s/trekkie/ — theme analytics snippets
Store's own domain (e.g. store.myshopify.com or custom domain) for any inline scripts

Platform code (discard — Shopify core infrastructure only)

Errors originating here are non-actionable — no merchant or app vendor can fix them:

cdn.shopify.com/shopifycloud/ — Shopify platform scripts
cdn.shopify.com/s/shopifycloud/ — same
checkout.shopify.com/ — Shopify checkout
monorail-edge.shopifysvc.com/ — Shopify analytics infrastructure
*.shopifysvc.com/ — internal Shopify service endpoints

Anything with its own support channel that isn't merchant-owned or telemetry — including Shopify-built products that operate independently of core infrastructure:

*.shopifyapps.com/ — Shopify app platform endpoints (each app has its own support)
shop.app/ — Shop app (separate Shopify product with its own support)
pay.shopify.com/ — Shop Pay (separate product)
static.klaviyo.com/, static-tracking.klaviyo.com/ — Klaviyo
heyethos.com/ — Hey Ethos (loyalty)
yotpo.com/, loox.io/ — reviews apps
Any third-party CDN not matching the store domain or Shopify core infrastructure above

Headless / custom frontend note

If this Shopify store runs a headless frontend (Next.js, Remix, Hydrogen, etc.), theme asset paths won't match the patterns above. Merchant code will be on the store's own CDN (Vercel, AWS CloudFront, etc.). In this case, classify by vendor script identification and ERR_TYPE — see references/platforms/generic.md.

Telemetry (discard)

Analytics, pixel, and beacon scripts — non-actionable, discard silently:

connect.facebook.net/ — Meta Pixel
www.google-analytics.com/ — Google Analytics
cdn.heapanalytics.com/, heapanalytics.com/, heap-api.com/ — Heap (CDN + API endpoints)
js.posthog.com/ — PostHog
snap.licdn.com/ — LinkedIn Insight Tag
sc-static.net/ — Snapchat Pixel
bat.bing.com/ — Microsoft/Bing Ads
cdn.segment.com/ — Segment
cdn.amplitude.com/ — Amplitude
analytics.tiktok.com/ — TikTok Pixel
cdn.shopify.com/shopifycloud/analytics-next/ — Shopify analytics beacon

HTTP errors without JS stack traces

Any 4XX or 5XX error with no JavaScript stack trace is classified as Platform and discarded — not fixable by merchant code. On Shopify this is most commonly bot/abuse protection (403, 429) or missing assets (404).
