Publish SAP CAI Chatbot over Amazon Alexa as a Skill

Hello everyone,

I would like to have a SAP Conversational AI Chatbot certified and published as a skill via the Alexa Developer Console. Unfortunately I encountered some bugs that I can't fix. Publishing the skill is not possible without fixing the errors. An error that occurs frequently would be, for example:

"The skill end-point is not validating the signatures for incoming requests and is accepting requests with an empty signature URL."

or

"The skill end-point is not validating the signatures for incoming requests and is accepting requests with an incorrect certificate URL."

All existing errors can be seen in the screenshot/attachment. Is there anyone among you who has published an Amazon skill with an SAP CAI chatbot as endpoint?

I am looking forward to a positive feedback.

Many greetings
