Why / What / How

Why: get_trial_offer logs Invalid card-required-trial-offer; refusing trial enrollment at ERROR on every eligibility check in production — roughly four lines per 20 minutes into platform_server_errors and Sentry since the v0.8.0 rollout. Nothing is broken: the card-required-trial-offer flag simply has two variations, and the one production serves is {"enabled": false}. That object is not null, so it reached TrialOffer.model_validate, failed extra="forbid", and took the error path. Dev serves the real offer, so the noise never showed there.

What: a flag payload that never claims to be an offer — no version key, or not an object at all — is now read as "no offer configured" and logged at DEBUG. A payload that carries version and still fails validation keeps its ERROR: that one is a broken offer someone has to fix.

How: version is the discriminator because TrialOffer requires it with no default, so every offer that can validate carries it and no disabled variation does. The guard sits before model_validate, matching how the two sibling LaunchDarkly JSON-object consumers (_fetch_cost_limits_flag, get_tier_stripe_price) narrow a raw flag value.

Return values are unchanged for every possible flag value — None in, None out, exactly as before, for the disabled variation and for a broken offer alike. Only the log level moves, so no caller behaviour changes.

Changes 🏗️

• subscription_trial_config.py: get_trial_offer returns None at DEBUG for a non-offer flag value instead of falling through to the ERROR handler.
• subscription_trial_config_test.py: the disabled variation and the other non-offer shapes produce no record above DEBUG; a version-carrying offer that fails validation still produces exactly one ERROR.

The LaunchDarkly side is unchanged and is not part of this PR.

Verified

I ran backend/data/subscription_trial_config_test.py (43 passed), backend/util/architecture_test.py and backend/blocks/test/test_block.py (1755 passed, 84 skipped), and ruff check on both changed files. I read production's flag configuration through the LaunchDarkly REST API to confirm the premise rather than inferring it. I mutated the fix back to the original if raw is None shape and confirmed the new tests fail — 5 failed / 38 passed. Evidence in a comment below.

The two consumers of get_trial_offer (subscription_trial_routes.py, subscription_trial_checkout.py) both branch on is None; I reasoned about them from the call sites rather than executing their suites, on the grounds that the return value is provably unchanged.

Checklist 📋

For code changes:

• I have clearly listed my changes in the PR description
• I have made a test plan
• I have tested my changes according to the test plan:
  • The disabled variation {"enabled": false} returns None and logs nothing above DEBUG
  • None, False, {} and {"enabled": true} behave the same way
  • An offer carrying version that fails validation still logs exactly one ERROR and returns None
  • A valid offer still parses
  • Reverting the guard turns the new tests red

🤖 Evidence

The premise, read from LaunchDarkly

card-required-trial-offer in production, via the REST API (values elided where they are product terms rather than evidence):

variations:
  0 {"enabled": false}
  1 {"version": "pro-equivalent-v1", ...the real offer...}
on: True
offVariation: 0
fallthrough: {"variation": 0}
rules: 0
targets: []

The flag is on with no rules and no targets, so its fallthrough serves variation 0 to every user. {"enabled": false} is not null, so before this PR it reached TrialOffer.model_validate and took the ERROR path on every eligibility check. Variation 1 is the only one carrying version, which is what the new guard keys on.

Mutation

Restoring the original if raw is None: return None and re-running the module:

FAILED test_flag_value_that_is_not_an_offer_is_silent[flag_value0] - assert [<LogRecord: ... enrollment">] == []
FAILED test_flag_value_that_is_not_an_offer_is_silent[flag_value1] - assert [<LogRecord: ... enrollment">] == []
FAILED test_flag_value_that_is_not_an_offer_is_silent[flag_value2] - assert [<LogRecord: ... enrollment">] == []
FAILED test_flag_value_that_is_not_an_offer_is_silent[None]        - AssertionError: assert [] == ['No card-req...r configured']
FAILED test_flag_value_that_is_not_an_offer_is_silent[False]       - assert [<LogRecord: ... enrollment">] == []
=================== 5 failed, 38 passed in 21.69s ===================

The four object/bool cases fail because the unpatched code emits the ERROR the PR exists to remove; the None case fails because it emits no record at all. test_offer_that_fails_validation_is_still_an_error stays green under the mutation, which is correct — the fix does not touch that path.

The log assertions attach a plain logging.Handler to the module logger rather than using caplog, which captures nothing for backend.* loggers under this app's logging config.

Test runs

backend/data/subscription_trial_config_test.py ....... 43 passed in 26.81s
+ backend/util/architecture_test.py .................. 46 passed in 59.38s
backend/blocks/test/test_block.py ......... 1755 passed, 84 skipped in 38.50s
ruff check <both changed files> ............ All checks passed!

Note for whoever merges second

#14799 also touches subscription_trial_config.py and its test module — it adds fields to TrialOffer and appends tests, and does not change get_trial_offer's body. The two should merge cleanly; if they do conflict it will be at the end of the test file, and both sides are keeps.

Walkthrough

get_trial_offer now treats flag values without an offer version as unconfigured and returns None. Tests cover non-offer values and confirm that invalid offer data still produces an error log.

Changes

Trial offer flag handling

Layer / File(s)	Summary
Handle unconfigured and invalid offers autogpt_platform/backend/backend/data/subscription_trial_config.py, autogpt_platform/backend/backend/data/subscription_trial_config_test.py	The guard returns None for non-dictionary flag values and dictionaries without a version key. Tests check non-offer values and their logs, and confirm that invalid offer data still produces an error log.

🤖 Review of 0ab9a24 posted: #14802 (review)

[autogpt-pr-reviewer]

✅ Verdict: Approved — No findings require changes before approval; this review counts as an approval.

A well-scoped log-severity fix that downgrades a false-positive ERROR to DEBUG when the trial-offer flag serves its disabled variation, while preserving ERROR alerts for genuinely broken offers. Return values are provably unchanged for all inputs, both callers are unaffected, and targeted tests cover both branches.

Validation and specialist details

Specialist Reports

Specialist	Status	Summary
security	✅ PASS	Logging-level-only change in get_trial_offer that narrows the pre-validation guard; validation is not weakened, return values and enrollment gating are provably unchanged, and no user-controlled data or secrets are exposed.
architect	✅ PASS	Minimal, well-scoped log-severity fix that narrows a raw LaunchDarkly flag value before validation, matching an existing sibling pattern with return behavior provably unchanged and good test coverage.
performance	✅ PASS	Two-line guard on a hot path that skips Pydantic validation for the disabled flag variation and cuts steady-state error-pipeline load; no performance regressions found.
testing	✅ PASS	Small, well-targeted log-level fix with strong, regression-catching tests that pin both the new DEBUG path and the preserved ERROR path; no blocking defects.
quality	✅ PASS	Clean, well-tested log-level fix that is provably behavior-preserving and follows the established raw-flag-narrowing convention; no defects found.
product	✅ PASS	Correct, well-scoped logging-level fix that silences false-positive ERRORs for the flag's disabled variation while preserving ERROR alerts for genuinely broken offers, with return values provably unchanged for all inputs.
discussion	✅ PASS	CI is green on head 0ab9a24 and there are no open human-reviewer requests.
ui-reviewer (local)	✅ PASS	Correct, well-tested backend logging fix: a non-offer flag value is now DEBUG instead of ERROR while return values and caller behavior are provably unchanged.
ui-reviewer (hosted)	✅ PASS	Correct, minimal backend fix that downgrades a benign non-offer flag payload from ERROR to DEBUG while preserving ERROR for genuinely broken offers; return values are unchanged for all flag values, no caller behavior changes, and the 43 targeted tests pass.
