API Failure: Share with new user

I have attempted using a sharing test with our Owncloud 10.1.1 instance (which already works for create / upload testcases in this repository).

but consistently to receive a 401 Unauthorized response, even when the headers included a valid Authorization header (basic auth).

The following was the response body returned:

<?xml version="1.0"?>
<ocs>
    <meta>
        <status>failure</status>
        <statuscode>997</statuscode>
        <message>Unauthorised</message>
    </meta>
    <data/>
</ocs>

Testcase
Share with new user

By comparing the request with that in the Owncloud web user interface, the frontend is also sending the header
OCS-APIREQUEST: true

Once I change share.ts to include this header specifically, and re-compile and re-run, the test passes without any issue.

Is this required to be added to specific endpoints, or at a global level? I'm unsure why this is required in this case and wanted to confirm more details before submitting a PR.

Start with the Share with new user testcase in src/k6/src/test/issue/github/ocis/1399/share_with_new_user.ts and the request implementation in src/k6/src/lib/api/share.ts. Compare the failing request with the Owncloud web UI request, then determine whether OCS-APIREQUEST: true is needed only for sharing endpoints or globally. Done means the testcase passes against Owncloud 10.1.1 with the confirmed scope.
