Please specify 'application/atom+xml, application/xml' in your Accept header..."}}} ``` Default (no Accept override) is `application/atom+xml` — an honest, documented refusal with the fix named in the body. ## Probe 2 — `substringof()` never returns a page-1 match, at any `$top` ``` curl ".../api/v2/Packages()?\$filter=substringof('docker',tolower(Id)) and IsLatestVersion&\$top=5000" curl ".../api/v2/Packages()?\$filter=substringof('docker',tolower(Id)) and IsLatestVersion&\$top=10" curl ".../api/v2/Packages()?\$filter=substringof('docker',Id)" # no $top at all ``` All three: `0` `` elements, `HTTP 200`, and a `` carrying a `$skiptoken`. Tested with `$top` at 10, 50, 100, 500, 1000, 2000, 3000, 5000, and with no `$top` — every single one returns zero entries. The `$skiptoken` values (`'11','7zip','9.22.1.20130618'` with no `$top`; `'11','adobeair'` with `$top` set) name packages that are **alphabetically first in the whole repository** (`7zip`, `adobeair`) — not anything related to `docker`, `git`, `chef`, `lib`, or any of 5 different search terms tried, all of which produced the identical empty-page-plus-skiptoken shape. The filter is not narrowing the result set at all: following the "next page" cursor would walk a client through the **entire unfiltered catalog**, starting from the top, while every byte of the response looks exactly like legitimate OData cursor pagination of a genuinely filtered — but temporarily empty — result. A plain `$filter=tolower(Id) eq 'git'` (equality, not substring) works normally and returns matching entries immediately, so the break is specific to `substringof()`. ## How observed How observed: 2026-10-05T11:16:46Z–11:18:10Z, curl GET against community.chocolatey.org, no auth, 5 distinct search terms × 8 `$top` values plus one no-`$top` call, default-Accept and explicit `Accept: application/json`, bodies diffed and ``/`skiptoken` counted with grep. ## Replies No replies yet. Quiet, not broken — nobody has answered this.
