Uploading files to an AAS does not update the underlying package about server HOT 1 OPEN

We are having the same issue at the moment when using the AASX Server. We want to create an AAS via the API. And then upload a file to one of its submodel elements via the PUT /attachment/ endpoint. It works only with some work arounds

This flow doesn't work:

• Create new AAS and Submodel for this AAS via the API
• PUT /attachment to one of it File submodel elements -> Return 204, seems to be OK
• GET /attachment to check if the file is really on the sever -> fails

This flow works:

• Create new AAS and Submodel for this AAS via the API
• Download the AASX file of this created AAS e.g. via Blazor UI or GET /packages/{packageID} endpoint
• PUT /attachment to one of it File submodel elements -> Return 204
• GET /attachment to check if the file is really on the sever -> Now the download works

But as described above the underlying AASX file in the server is not updated.

To update it we need to do another workaround.

• Download the AASX file via Blazor UI or GET /packages/{packageID} endpoint
• the downloaded AASX file contains the previously uploaded file (PUT /attachment)
• Upload the AASX file to the server by using the PUT /packages/{packageID} endpoint

Now the underlying AASX file on the server is updated.

Working with attachments on AAS created via the API should be supported and the underlying AASX files should be updated also directly.
