error in slice submit : `refresh_token` must not be `None`

[Gregory Daues]

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 be None

for 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__.py

Also, 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==1.3.0

Thanks 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 :

Could you please invoke the show_config() and share the output before invoking new slice?
Also, could you please verify that the token file has refresh_token and json looks like below:

P.S: You may already have it in correct format.

{"id_token": "YOUR ID Token",
"refresh_token": "YOUR Refresh Token",
"created_at": "timestamp"}

fablib.default_fablib_manager = FablibManager()

fablib.show_config()

show_config would list the token file being used, please verify that it is correct.

Thanks,

Komal

[Gregory Daues]

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?

[Paul Ruth]

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
