It would seem like the artifactory search is broken in version 7.41.7, maybe related to conan search improvements in 7.41.4.
Problem is that info and install commands run in against the artifactory results in error like "ERROR: Loop detected in context host: 'qtwebview/6.3.1@qt/everywhere' requires 'qtwebview/6.3.1@qt/everywhere' which is an ancestor too" etc.
It would seem that after the call to https://qtpkgtest.jfrog.io/artifactory/api/conan/qt-dist/v2/conans/search?q=qtbase%2F%2A%40qt%2Feverywhere&ignorecase=False
it starts to fetch qtwebview which is not dependency for the qtsvg being installed nor should it be any other way included.
In fact the call above returns all modules and version in the artifactory. Qtwebview being last module on the list.
Same happens on the conan client "conan search -r dist qtbase*" returns all modules (qtsvg, qtwebview, etc) not just qtbase.
