scripts/vercel-ignore.sh skipped any preview deploy where
VERCEL_GIT_PULL_REQUEST_ID was empty. Vercel only populates that var
on fresh PR-aware webhook events; manual "Redeploy" / "Redeploy
without cache" from the dashboard, and some integration edge cases,
leave it empty even on commits attached to an open PR. The merge-base
diff against origin/main below it is already the authoritative
"touched anything web-relevant" check and is strictly stronger.
Repro: PR #3403 commit 24d511e29 on feat/usage-telemetry — five api/
+ server/ files clearly modified, build canceled at line 18 before
the path diff ran. Local replay with PR_ID unset now exits 1 (build).

# We deliberately do NOT gate on VERCEL_GIT_PULL_REQUEST_ID. Vercel only
|
|
# populates that var when the deploy is triggered by a fresh PR-aware
|
|
# webhook event; manual "Redeploy" / "Redeploy without cache" actions
|
|
# from the dashboard, and some integration edge cases, leave it empty
|
|
# even on commits that are clearly attached to an open PR. Gating on it
|
|
# silently cancels legitimate previews (PR #3403 incident: 24d511e on
|
|
# feat/usage-telemetry, all 5 api/ + server/ files skipped).
|
|
#
|
|
# The merge-base diff below is the authoritative "did this branch touch
|
|
# anything web-relevant" check, and it's strictly stronger than the
|
|
# PR-ID guard: branches with no web changes still skip via that diff,
|
|
# branches with web changes build whether or not Vercel happens to know
|
|
# about a PR association at deploy time.
|
|
#
|
|
# Why merge-base is preferred over PREVIOUS_SHA: on a branch's FIRST
|
|
# push, Vercel has historically set VERCEL_GIT_PREVIOUS_SHA to values
|
|
# that make the path-diff come back empty (the same SHA as HEAD, or a
|
|
# parent that sees no net change), causing "Canceled by Ignored Build
|
|
# Step" on commits that genuinely touch web paths (PR #3346 incident).
|
|
# merge-base is the stable truth: "everything on this branch since it
|
|
# left main", which is always a superset of any single push.
|
|
#
|
|
# PREVIOUS_SHA stays as the fallback for the rare shallow-clone edge
|
|
# case where `origin/main` isn't in Vercel's clone and merge-base
|
|
# returns empty. This is the opposite priority from the main-branch
|
|
# block above (line 6), which correctly wants PREVIOUS_SHA = the last
|
|
# deployed commit.
