Python API not running as wanted

methusi

Hi

I am really new to RM and the whole ecosystem. For a student project I deployed a RM AI Hub on a server with the docker deployment which works all as expected. But if I try to run a process via python I get an error and have no clue how to solve that issue.
Python snippet:

import rapidminer
connector = rapidminer.Server(
    "http:// myserver",
    username="username",
    password="password")

As of the output I can see that the connection to the server is established successfully.
I created a webservice, but I am not sure if that makes any difference.

I am glad for any help - thanks a lot :-)

See the full output below:

Hi @methusi,

Thank you for your patience.

Apologies for the misleading error message. We'll improve it.

The true cause is most likely that Basic authentication is disabled. You can enable it in the .env file by changing the property below to true:

LEGACY_REST_BASIC_AUTH_ENABLED=true

You'll need to restart the stack with docker-compose.

Let me know if this helps.
Best,
Peter

Hey @methusi,

Thanks for the report, we are looking into this.

A quick question: have you noticed the whitespace in "http:// myserver"?

Best,
Peter

Hi @phellinger

Thanks a lot for looking into it.

I am aware of that whitespace. I removed the IP and had to enter such a whitespace to be able to post the question.

Best,
Mathis
