For either Fabric Release 1.2.x or 1.3 client-side I am now seeing an error in slice submit :
ValueError: Invalid value for
refresh_token, must not beNonefor scripts that were working, say early August. Is there an update for settings for tokens client side ?
I have the standard FABRIC_TOKEN_LOCATION set.Hi Gregory,
Thank you for reporting this issue. Could you please share the snapshot of the stacktrace if available where this error is observed or share your notebook?
Also, could you please share the output of the command below?
cat /opt/conda/lib/python3.9/site-packages/fabrictestbed/__init__.pyAlso, are you using the Jupyter Hub or local desktop environment?
If you are using the desktop environment, please consider updating the python environment using the following command:
pip install fabrictestbed-extensions==1.3.0Thanks and Regards,
Komal
I am working in a bash shell (‘local desktop’) and 1.3.0 is installed .
The lib/python3.9/site-packages/fabrictestbed/__init__.py shows__VERSION__ = “1.3.0”
and the lib/python3.9/site-packages/fabrictestbed_extensions/__init__.py shows
#
__VERSION__ = “1.3.0”
I’ll try to gather more details.
The stacktrace looked like the following :

Yes it looks like a matter of an invalid or corrupted token. Somehow I ended up working with a token with
these contents:> cat cmbs4_1_tokens.json
{“id_token”: null, “refresh_token”: null, “created_at”: “2022-09-01 15:31:47”}
I have since worked through the credential manager , and downloaded a token with valid entries,
and slice submission has succeeded. So I guess I may have worked through the credential manager with an expired session(?) or something to obtain / download such a malformed token.
So I think my issue is resolved, where I will examine the downloaded tokens as a check.Thanks,
Greg
I am getting :
“Exception: b'{\n “errors”: [\n {\n “details”: “(invalid_grant) invalid refresh token”,\n “message”: “Internal Server Error”\n }\n ],\n “size”: 1,\n “status”: 500,\n “type”: “error”\n}'” as shown in the picture.
What am I doing wrong?
The most likely reasons for this are either the token expired or you config is not pointing to the valid token.
If you are in the FABRIC JupyterHub, you can get a new token by logging out the back in. If you still see this error then you should confirm you configuration is correct. You can print you configuration with
fablib.show_config(). The default location of the token in the FABRIC JupyterHub is:/home/fabric/.tokens.json
