I also attach a demo AASX file (please rename to aasx) jsonAO2000docs.zip

Thanks!

Hi Sten,

we found the problem in the AAS Environment (when using the preconfiguration and the /serialization endpoint. Both currently don't support serializing/deserializing aasx files with json content. Since this is already implemented in aas4j it should be an easy fix.

For reference here is the link to aas4j with the method to be used: aas4j AASXSerializer

Changes need to be made here:

• AAS Environment serialization
• AAS Environment Loader

I will put this ticket in our backlog so that it can be implemented in the next weeks.

We are waiting for a new release from AAS4J, because we need the aas4j AASXSerializer methods.
