I'm creating a watcher to check some values with an API Restful. It is failing with this error:
[2018-02-22T19:07:00,941][ERROR][o.e.x.w.i.h.ExecutableHttpInput] [kibana] failed to execute [http] input for watch [inlined], reason [sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target]
The API is listening in HTTPS but it is self-signed. I don't find any attribute to skip the certificate verification: https://www.elastic.co/guide/en/x-pack/current/input-http.html#http-input-attributes.
