github-actions · 2026-09-24T09:03:19Z

Synchronizes main into beta. Merge this PR after CI passes. This updates the beta branch but does not publish a beta package.

## Summary - create a reviewable sync PR from main to beta after each main push - run the ci-ok check for pull requests targeting beta - document beta synchronization and protection requirements ## Validation - actionlint - git diff --check The beta ruleset could not be created from this session because GitHub API write operations are blocked by the sandbox. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

## Summary - restrict beta manual publishing to workflow dispatches run from the beta branch - document the required beta-branch dispatch Supersedes #46, which conflicts because #45 was squash-merged. ## Validation - actionlint - git diff --check Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

## Summary - document stable-only and beta-first release flows - document how to resolve beta synchronization release-state conflicts - restore repository scoping and explicit GitHub CLI failure handling in the beta sync workflow ## Validation - actionlint - git diff --check Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

## Summary - configure the beta Release Please workflow with target-branch: beta - prevent beta release runs from using main release state or updating main Release PRs ## Validation - actionlint - git diff --check Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

## Summary - configure Release Please's prerelease versioning strategy for beta releases - retain the beta prerelease GitHub Release flag and beta version identifier ## Validation - JSON validation - git diff --check Supersedes beta Release PR #57, which generated a plain version because the versioning strategy was omitted. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

## Summary - accept both valid Release Please beta suffix forms: -beta and -beta.N - correct beta release version examples in the release guide ## Validation - actionlint - git diff --check - exercised guard matching for beta, beta.1, and stable versions Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Major version bumps (e.g. vitest 4->5) were silently grouped together with safe minor/patch bumps, risking breaking changes landing unreviewed. Majors now get their own separate PR. Co-authored-by: sindrerh2 <--global>

…#87) ## Problem Multiple teams reported CORS preflight failures on `dev-gcp` when calling `https://telemetry.ekstern.dev.nav.no/collect`: ``` Access to fetch at 'https://telemetry.ekstern.dev.nav.no/collect' from origin 'https://borger.ansatt.dev.nav.no' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. ``` The origin **was** correctly allowlisted server-side (verified via direct `curl` preflight tests). The actual cause: `@grafana/faro-web-sdk@2.12.0` (pulled in transitively via `@nais/apm`'s previous `^2.11.0` range, and directly bumped to `^2.12.0` on `main` by dependabot in #84) unconditionally sends an `Idempotency-Key` request header on every request as of [grafana/faro-web-sdk#2264](grafana/faro-web-sdk#2264) ("make reliable Fetch transport the default"), **with no opt-out**. The `Alloy` `faro.receiver` component nais runs (via `nais/helm-charts` `features/alloy-faro`) hardcodes its allowed CORS request headers in Go and does not yet include `idempotency-key`. That fix ([grafana/alloy@a6e19ce](grafana/alloy@a6e19ce), merged 2026-09-09) has only shipped in the unreleased `v1.20.0-rc.0` — no stable Alloy release contains it yet, including the `1.12.1` currently pinned in `features/alloy-faro/Chart.yaml`. Per the [Fetch CORS spec](https://fetch.spec.whatwg.org/#cors-preflight-fetch), when *any* header in `Access-Control-Request-Headers` isn't in the receiver's allowlist, the **entire preflight is aborted** — no `Access-Control-Allow-Origin` is set at all, even though the origin itself is valid. This makes a header allowlist problem look exactly like an origin allowlist problem. ## Fix Pin `@grafana/faro-web-sdk` (dependency) and `@grafana/faro-react` (devDependency, used only for our own peer-compatibility tests) to the exact `2.11.0` release — the last version before the unconditional `Idempotency-Key` header was introduced. ## Verification - `pnpm test` — 244/244 tests pass - `pnpm build` — succeeds - Manually reproduced the failing preflight against `https://telemetry.ekstern.dev.nav.no/collect` with `Access-Control-Request-Headers: content-type,idempotency-key,x-faro-session-id` → 204 with no `Access-Control-Allow-Origin`. Removing `idempotency-key` from the request restores the header, confirming this is header- not origin-related. ## Follow-up Un-pin once nais's Alloy deployment is confirmed upgraded past `v1.20.0` in all clusters (or a backported patch release ships `idempotency-key` support earlier).

fix(deps): exclude major bumps from npm-all Dependabot group (#81)

c270040

Major version bumps (e.g. vitest 4->5) were silently grouped together with safe minor/patch bumps, risking breaking changes landing unreviewed. Majors now get their own separate PR. Co-authored-by: sindrerh2 <--global>
