Hi, I am getting an error during the functional test of my skill:
"The skill is using an invalid certificate URL chain."
The result of the functional test referres to https://developer.amazon.com/docs/custom-skills/host-a-custom-skill-as-a-web-service.html#cert-verify-signature-certificate-url but the certification validation is implemented and used by the JAVA SkillServlet of the ask-sdk which I am using in version 2.5.0
I am using a custom endpoint and have created a ssl certificate with letsencrypt which was accepted by Amazon.
Testing with console works fine.
Thanks for your help!
