fix(track): don't drop increment/decrement for a not-yet-created profile - #473
Conversation
adjustProfileProperty threw HttpError 404 ('Profile not found') when
getProfileById returned nothing, and 400 when the existing value wasn't
numeric. Both cases silently drop the operation.
A missing profile is not an error condition here: an increment/decrement
routinely fires before the profile's first event or identify has landed
(a race), or for an anonymous/transient id. Rejecting it loses the delta
and never creates the counter.
Adopt Mixpanel $add / $subtract semantics: treat the current value as 0,
upsert (creating the profile if needed), and apply the delta. A
non-numeric existing value is skipped rather than 400'd, and is never
overwritten with NaN. Existing numeric profiles are unaffected.

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The change makes increment/decrement create missing profiles and skip nonnumeric values, but concurrent updates can still be lost, malformed values can be applied incorrectly, nested data can be overwritten, and writes may appear successful before persistence.

Use strict numeric validation. adjustProfileProperty reads arbitrary profile-property values and passes the leaf value to Number.parseInt. Therefore, "12abc" becomes 12 and "1.5" becomes 1, then the handler persists the incorrect adjustment. Validate the value with Number(...), a non-empty check, and Number.isFinite(...) before updating.

Ramda 0.29.1 assocPath pathOr behavior non-object intermediate path node
💡 Result:
In Ramda 0.29.1, the behaviors of assocPath and pathOr regarding non-object intermediate paths differ fundamentally based on their purposes: construction vs. retrieval [1][2]. assocPath Behavior When assocPath encounters a missing or non-object value at an intermediate path level, it creates a new structure to accommodate the specified path [3][2]. To determine what type of structure to create (an Array or an Object), assocPath inspects the next key in the path: If the next key is an integer (e.g., 0, 1, 4), Ramda creates an Array [4][3]. If the next key is not an integer (e.g., 'a', 'key'), Ramda creates an Object [3]. For example: R.assocPath(['a', 'b', 'c'], 42, {a: 5}); // => {a: {b: {c: 42}}} (replaces primitive 5 with an object) [1][2] R.assocPath(['a', 1, 'c'], 42, {a: []}); // => {a: [undefined, {c: 42}]} (creates index 1 as an object within an array) [2] pathOr Behavior pathOr is designed for safe data retrieval and does not create structures [5]. If any part of the path is missing or does not exist on the object, pathOr will immediately return the provided default value [5]. Important nuances for pathOr: It evaluates whether a path exists by checking if the object "has" the property, but its handling of null/undefined values has historically been a subject of internal debate [5][6]. It returns the default value if the path cannot be resolved (i.e., it is effectively "missing") [5]. It is generally inconsistent with propOr regarding how they treat keys that exist but are explicitly set to undefined, a known point of contention in the library [7][5]. Summary of Key Differences: - assocPath is constructive: It forces the object structure to match the provided path by overwriting primitives or missing nodes [1][2]. - pathOr is retrieval-only: It never modifies the source object and simply falls back to the default value if the path is not found [5].

Preserve non-object intermediate properties.
When property is a.b and properties.a is "keep", pathOr returns "0". assocPath then replaces a with an object, and upsertProfile persists the replacement through ProfileBuffer. Skip the update when an intermediate path value is not an object. Use 0 only when the target leaf is absent.

Serialize concurrent adjustments for one profile.
Two requests can both read a missing profile, calculate from 0, and upsert the same resulting snapshot. Under the supplied latest-row-wins contract, one increment or decrement is lost. Use an atomic adjustment or serialize updates per profile before writing the snapshot.

Summary
increment/decrement(adjustProfileProperty) currently drops the operation when the target profile doesn't exist yet, or when the existing value isn't numeric. This changes it to follow Mixpanel$add/$subtractsemantics — treat the current value as0, create/upsert the profile, and apply the delta — so the counter is preserved instead of lost.The problem
A missing profile here is not an error condition — it's a normal race. An
increment/decrementlegitimately fires:track/identifyevent has landed (the profile row is created lazily by those, so a counter op that arrives first finds nothing), orIn both cases the current code rejects the request and the increment is silently lost — the counter is never created, and the client has no way to recover it. This diverges from Mixpanel's
$add/$subtract, which create the profile and start the property from0.The
NaNbranch has the same shape: a single non-numeric value on the property400s the whole request rather than being skipped.The fix
0 + deltaCompatibility

main+ this single commit (clean diff onadjustProfilePropertyonly).HttpErrorremains used elsewhere in the file, so its import is untouched.Error(→ retryable 500 rather than a 404), the SDK retried each failure and amplified a handful of unique increments into a 5xx storm. Upstream's404isn't retryable so it won't storm — but the underlying lost-increment behaviour is the same, which is what this PR addresses. Happy to add tests in the style you prefer if this direction looks good.Summary by CodeRabbit
