I am using HTTPRequest node to make requests using TLS. Is there a way to skip certificate validation (checking the certificate chain, the expiration date) with standard IIB settings? I know this is risky.
In order to do this kind of things, there is a lot of workaround, but they are not that easy and quite horrible. I would suggest you to use a JavaCompute Node, using unix curl/wget commands for example (if running on Unix), or any other solution that is working on Java.
But I can confirm, you cannot use the default IIB nodes (like HTTPRequest) for this purpose.
