fix(error-tracking): drop --region flag from source maps wizard command by ablaszkiewicz · Pull Request #73263 · PostHog/posthog

ablaszkiewicz · 2026-07-23T15:02:09Z

Problem

The source maps upload recommendation tells users to run npx -y @posthog/wizard@latest upload-source-maps, and on EU Cloud we appended --region eu. The wizard already resolves the region from the access token, so the flag is redundant noise in the command we hand people.

Changes

Drop the --region eu suffix everywhere the source maps recommendation renders the wizard command:

weekly_digest.py — _source_maps_wizard_command() now returns the plain command
missing_source_maps.py health check — WIZARD_COMMAND constant (also drops the now-unused get_instance_region import)
sourceMapsFixWizardLogic.ts — wizardCommand selector is now a constant (drops the preflightLogic / Region dependencies)
error-tracking-recommendations-list.md MCP prompt — removes the "append --region eu for EU projects" note

Left the headless cloud-run wizard in products/tasks/.../run_wizard.py untouched: it runs non-interactively in a sandbox where a local access key can't infer a region, so it passes --region deliberately.

How did you test this code?

Ran TestSourceMapsRecommendationForDigest (7 passed). Removed the now-obsolete test_wizard_command_appends_region_eu_on_eu_cloud case. Frontend typecheck shows no errors in the touched logic.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

I (Claude) made this change on request. Swept the repo for --region appended to the wizard command, found four recommendation surfaces plus the headless task runner, and changed only the four user-facing recommendation spots. No skills were required for this change.

The @posthog/wizard upload-source-maps command auto-detects the region from the access token, so the appended --region eu flag is redundant. Remove it from all four places the recommendation surfaces it: the weekly digest, the health check remediation, the frontend fix modal, and the MCP recommendations prompt.

✅ Toolbar bundle — eager 2.18 MiB within budget

What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

Metric	Size	Δ vs base	Budget
Eager (shipped) entry + static imports	2.18 MiB · 17 files	no change	`████░░░░░░` 38.1% of 5.72 MiB

…logic The wizardCommand selector no longer has input dependencies, so kea-typegen drops the generated Meta interface and simplifies MakeLogicType. Commit the canonical output so the frontend typegen check passes. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
