In the example from 7.57.0 it's only necessary to set CAINFO to NULL to
resolve the issue. The updated example which is now official [1] I set
both CAINFO and CAPATH to null but now neither is necessary. The former
will load the certificates which would take time and the latter there
seems to be no time effect (but it's not guaranteed since it depends on
inner workings of OpenSSL). Therefore both are now null in the example
and tagged optional. I would encourage you to use the updated example.
