Problem

East Herts retired AchieveForms lookup 683d9ff0e299d. The runLookup call still answers HTTP 200, but the body is {"error": "User Package Not Found"}, so EastHertsCouncil crashes with KeyError: 'integration' and the API server returns 500.

What changed on the council side (checked 2026-11-06)

  • The "When are my Bin Collection days?" form now calls lookup 6accfd6441228.
  • Unchanged: the form and process URIs (AF-Process-98782935-..., AF-Stage-dcd0ec18-...), the posted field (Collection Days / inputUPRN), and the response path (integration.transformed.rows_data["0"], with *ServiceName / *NextDate keys).
  • Service names now come wrapped in newlines and spaces.

Plain HTTP still works. No Selenium needed.

Fix

  • Use the new lookup id.
  • Raise a ValueError naming the council's message when the lookup returns an error body, so the next form change is obvious.
  • Strip whitespace from service names.
  • Sort bins by collection date.

Tests

  • New uk_bin_collection/tests/test_east_herts_council.py (4 tests, mocked HTTP).
  • pytest uk_bin_collection/tests custom_components/uk_bin_collection/tests --ignore=uk_bin_collection/tests/step_defs/: 506 passed.
  • pytest uk_bin_collection/tests/step_defs/ -k EastHertsCouncil: passed (live, test UPRN from input.json).
  • Live output for the test UPRN: Food Waste (Caddy) 10/11/2026, Refuse (Purple) 10/11/2026, Garden 12/11/2026, Mixed Recycling (Black) 17/11/2026, Cardboard and Paper (Blue) 24/11/2026.

input.json is unchanged: the inputs are the same (UPRN only).

Summary by CodeRabbit

  • Bug Fixes
    • Improved East Herts collection lookups by handling council-reported errors, trimming extra spaces from service names, and ordering collections by date.

East Herts retired AchieveForms lookup 683d9ff0e299d. It still answers
HTTP 200, but with {"error": "User Package  Not Found"}, so the scraper
crashed with KeyError: 'integration'. The "When are my Bin Collection
days?" form now calls lookup 6accfd6441228. The form and process URIs,
the posted field (Collection Days / inputUPRN) and the response path
(integration.transformed.rows_data["0"]) are unchanged.

- Use the new lookup id.
- Raise a ValueError naming the council's message when the lookup
  returns an error body, so the next form change is obvious.
- Strip the whitespace the council now wraps around service names.
- Sort bins by collection date.

Walkthrough

East Herts lookup and response parsing now use an updated lookup ID, raise an error when the API response contains an error, trim service names, and sort bins by collection date. Tests cover each behavior.

Changes: East Herts council parsing

Layer / File(s) Summary
Lookup and parsed bin behavior
uk_bin_collection/councils/EastHertsCouncil.py, uk_bin_collection/tests/test_east_herts_council.py
The lookup request uses a new ID. The parser raises the API error message, strips whitespace from service names, and sorts bins by collection date. Tests cover these changes.

The lookup update is mergeable with normal checks. Additional error-message and cross-month ordering tests would strengthen coverage but are not blockers.

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 3 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Test more than one council error message.

The test accepts an implementation that always reports User Package Not Found. Add a second error message to check that the parser forwards the response message.

Add a cross-month ordering case.

Both fixture dates are in November, so sorting by day number alone would pass this test. Add dates such as 30 November and 1 December, and assert that 30 November comes first.

Thanks @Russell-IO. The East Herts lookup fix went out in 0.173.6, with your authorship kept. Closing as it's landed via the November release branch.
