fetchResource loads actual items from the API due to wrong queryParameter

[Sirs0ri]

API Platform version(s) affected: 2.6.8

Description

The API doc parser uses fetch() via the fetchResource() method to load API metadata, and fails to apply the query parameter { itemsperpage: 0 } correctly to limit the request to only metadata and no API items.

fetchResource() tries to set the query parameter via a secondary options parameter, however fetch() doesn't support that - params have to be part of the url instead.

// Current code:
fetchJsonLd(
  resourceUrl,
  Object.assign({ itemsPerPage: 0 }, options)
)

// Fixed code:
fetchJsonLd(
  resourceUrl + "?itemsPerPage=0",
  options
)

How to reproduce

Possible Solution

Replace the Object.assign() call with an URL including the query parameter, possibly by building an URL:

const url = new URL(resource.url);
const params = new URLSearchParams(["itemsPerPage", 0]);
url.search = params.toString();

fetchJsonLd(url, options)

Additional Context

Please excuse that my code examples are in plain JS, not TS, since I'm not familiar enough with typescript.

ping @soyuka @alanpoulain this one is a real bummer: in every list page of API Platform Admin, it causes a double fetch to the getList endpoint, one without params for introspection (but still returning data), and the other with the correct params.
