convert json into aasx fails

[Kuchsn]

Hey together, i try now since 3 days to read a json from Festo(Example) and safe it as a aasx file. But the file doesn't contain the expected data. What i am doing wrong?

from basyx.aas import model
from basyx.aas.adapter import aasx
from basyx.aas.adapter import json as aas_json
from basyx.aas.adapter import xml as aas_xml

##################################################################
# Step 1: Reading the Serialized AAS Objects From JSON/XML Files #
##################################################################
with open('./data/Festo.json', encoding='utf-8-sig') as json_file:
    json_file_data = aas_json.read_aas_json_file(json_file)

# For holding auxiliary files, which will eventually be added to an AASX package, we need a SupplementaryFileContainer.
file_store = aasx.DictSupplementaryFileContainer()

######################################################################
# Step 2: Writing AAS objects and auxiliary files to an AASX package #
######################################################################

with aasx.AASXWriter("./data/Festo.aasx") as writer:
    # Write the AAS and everything belonging to it to the AASX package
    # The `write_aas()` method will automatically fetch the AAS object with the given id

    #I don't know the id, so i iterate over every obj int the dictionary

    for obj in json_file_data:
        writer.write_aas(aas_ids=obj.id,
                     object_store=json_file_data,
                     file_store=file_store)
        writer.close()

Festo.json This programm end without an error. If i try to upload it on a local server:

import requests
# Define the endpoint URL
url = 'http://192.168.11.79:5001/packages'

# Specify the file path of the AASX file
aasx_file_path = './data/Festo2.aasx'

# Prepare the data to be sent in the POST request
files = {'file': open(aasx_file_path, 'rb')}

# Send the POST request
response = requests.post(url, files=files)

# Check the response
if response.status_code == 200:
    print("AASX file uploaded successfully.")
else:
    print("Failed to upload AASX file. Status code:", response.status_code)
    print("Response:", response.text)

i get this response:

  ]
}

i figured out, that "json_file_data" is empty?

with open('./data/Festo.json', encoding='utf-8-sig') as json_file:
    json_file_data = aas_json.read_aas_json_file(json_file)
print("Type of json_file_data:", type(json_file_data))
print("Number of AAS objects in json_file_data:", len(json_file_data))

Type of json_file_data: <class 'basyx.aas.model.provider.DictObjectStore'>
Number of AAS objects in json_file_data: 0

if i read the json normal i can see all

with open('./data/Festo.json', 'r') as file:
    data = json.load(file)
print(data)

i get this response:

Same issue as #185, the server you're using is probably using outdated OPC Relationship types.

As for the issue with the seemingly empty JSON file: It's possible that the file uses incorrect attribute names, that aren't recognized by our SDK. You can try validating this file against the official schemata using our compliance tool: https://basyx-python-sdk.readthedocs.io/en/latest/compliance_tool/index.html

Related to eclipse-aaspe #161 and #232 Edit: most aasx, json and xml EXAMPLE file are old specification!

Yes, that is the case. Currently, as far as I know, the IDTA has no maintenance process for submodel templates, therefore there is no one responsible for updating them. However, I have heard that they are aware of this problem and are working on a solution.
