REST-API get-request - Error: truncated response

[DanielToGo]

Hello community,

I'm working on a python project which needs the configuration data of a solution so I tried receiving it via get-request in the REST-API on my virtual core. The requests seems to work and it responds with a 200 code however I get an error message saying the "message is truncated" instead of the content. Getting a bearer Token via POST-Request works though and I also tried to request it with the same data via the ctrlX OS and Postman. Both work fine and I get the full JSON-Data.
Does anyone know what the problem is and how I can fix it?

Thanks in advance! Heres the code and its output:

head = {"accept": "application/json", 'Authorization': 'Bearer {}'.format(token)}
url = 'https://10.0.2.2:8443/solutions/api/v1/solutions/DefaultSolution/configurations'

with requests.get(url, headers=head, verify=False) as response:
    data = json.loads(response.text)
    print(response.json())
    print(data)
    print(response.status_code)
    print(response.text)

Hi @DanielToGo ,

I tried to reproduce your issue and was unable to. I recieve the entire response object.

Code

    url = 'https://10.0.2.2:8443/identity-manager/api/v1/auth/token'
    head = {"Content-Type": "application/json"}
    creds = {"name":"boschrexroth","password":"boschrexroth"}
    with requests.post(url, headers=head,verify=False,json=creds) as response:
        data = json.loads(response.text)
        token = data['access_token']
        print(data)
        print(response.status_code)
        print(response.text)

    head = {"accept": "application/json", 'Authorization': 'Bearer {}'.format(token)}
    url = 'https://10.0.2.2:8443/solutions/api/v1/solutions/DefaultSolution/configurations'

    with requests.get(url, headers=head, verify=False) as response:
        data = json.loads(response.text)
        print(response.json())
        print(data)
        print(response.status_code)
        print(response.text)

If you run this in a debugger and break on the response, can you view all of the data? Is it possible you have a character limit set on your print function?

What version of the VirtualCORE and Python requests lib are you using?

I would recommend using the datalayer client class rather than raw REST API for any datalayer operations.

Hey @Sgilk,

I tried testing it with the remote debugging instead of uploading it to the core and it immediately worked! It actually sends and prints out everything as you would expect. I didn't change anything in the print function but you might be onto something. There might be some kind of character limit in there for some reason.

Thanks for helping!
