Thanks for the PR, please make sure it is based on the latest master state and then do a composer i and ./build/openapi-checker.sh. That should remove all the unintended OpenAPI changes.

Also the changes in lib/composer have to be reverted

[provokateurin]

Ah I see what is going on, the lockfiles in vendor-bin have been changed and that is causing the OpenAPI changes. So please remove all changes except for lib/public.
