Having trouble trying to convert cbor object to CSR while trying to provision a device

[witch_mountain]

HI all, 

So after realizing that I needed to Just-In-Time provision my Thingy 91 in order to add the device to my nRF Cloud account, I began the process described in this post in the nRF documentation: Generating credentials using AT commands I had been able to successfully obtain the base64-encoded CBOR object and I'm trying to convert that into a CSR through this python script:  modem_credentials_parser.py 

I have the script downloaded and saved in the same folder that Python on my laptop is also saved in. I tried to follow the README.md associated with the script and I'm not able to make it past the required package installations. 

If I go ahead and try to use the script with my CBOR object I get

Traceback (most recent call last):
File "Z:\modem_credentials_parser.py", line 11, in <module>
from cbor2 import loads
ModuleNotFoundError: No module named 'cbor2'

I have both pip and cbor2 installed on my machine so I'm not sure what else I'm missing for these issues to keep coming up?

Hi,

I have inquired internally regarding the issue and will get back to you soon.

Hi,

The issue may arise if you are using a firewall. Maybe you could try using an unrestricted firewall and see if this helps.

Hi Priyanka! 

I'm accessing this through a work network and I've been in contact with my IT department and I was able to work through some of my issues and am now in this new position: 

After being able to configure pip to the CA certificate associated with my place of work I was able to create a virtual environment and update pip to the latest version without throwing an SSL error. I've added this new environment to my PATH and then tried to install my requirements.txt file in order to use the python script associated with my initial task ;-;

When I enter pip install -r requirements.txt I get the following error:

I was wondering if there was something else I'm missing when I try to install the requirements for the scripts needed.

Thanks!
