Unable to use fablib.manager

[Shams Gozalova]

Hi everyone,

I am new to FABRIC and trying to run a simple tutorial on Hello, Fabric, however I get stuck on the first ever step of the notebook. I have configured the environment with necessary details, but I keep running on token and project uuid problems. I am using the 1.6.0 version

The project ID that I am using is 488bd68e-9703-447b-bd77-069da4f438a6.

Here are the traces:

Before this, I was running on the error on the screen attached.

It is mentioned that the token should be refreshed automatically, but even when I try to generate a new one via hub portal and restart the service the issue pertains. Has anyone faced the same issue before? Any suggestions on how to resolve this?

Thanks in advance

Hi Shams,

Could you please remove <> enclosing the project id in /home/fabric/work/fabric_config/fabric_rc and restart your JH container via File -> Hub Control Panel -> Stop Container followed by Start Container?

Please try your notebook again and let us know if you still observe this error.

Thanks,

Komal
