TypeError: 'exceptions.ValueError' object is not callable, when using client.service.create()

Call to client.service.create() fails without understandable error with the following trace:

e = HTTPError(u'500 Server Error: Internal Server Error for url: http+docker://localunixsocket/v1.32/services/create',)

        try:
            explanation = response.json()['message']
        except ValueError:
            explanation = response.content.strip()
        cls = APIError
        if response.status_code == 404:

@feliperuhland sorry for the delay, from the python console all is working as expected:

So it seems not a library bug 👍 Using the lib wrapped around Flask is working too. I’m investigating further… the problem is limited to pytest + Flask test_client:

app = Flask(__name__)
appclient = app.test_client()
response = appclient.put('/deploy/deploy_test', content_type='multipart/form-data', data=data)

returns the well known E TypeError: 'exceptions.ValueError' object is not callable

Seems the library docker/errors.py:22 cls = APIError

can’t found the correct APIError class when using pytest + Flask test_client()

Thanks again for your support!

@shin- I think we can close this.
