Python 3.6 RuntimeError: 44 (AWS_ERROR_FILE_INVALID_PATH): Invalid file path..

Hi,

I've been debugging this issue for a while now and can't seem to pin point the cause. I keep getting this error when trying to "connect" using the ipc client.

I am running:

Ubuntu 18.04
awsiotsdk == 1.9.0
awscrt == 0.12.0
python 3.6

I am able to connect using the certificates on my device in other ways, so I don't believe it's a credentials issue.

Here is my output:

The item that I'm not understanding is here -- service.init: stderr. RuntimeError: 44 (AWS_ERROR_FILE_INVALID_PATH): Invalid file path.. What file path is invalid?

I can confirm the NUCLEUS_SOCKET environmental variable is set:

2022-02-07T20:46:01.821Z [INFO] (Copier) service.init: stdout. NUCLEUS_SOCKET_PATH: /greengrass/v2/ipc.socket. {scriptName=services.service.init.lifecycle.Bootstrap.Script, serviceName=service.init, currentState=NEW}

Also, here is my greengrass deployment with its necessary dependencies:

aws.greengrass.Cli | 2.5.3
aws.greengrass.DockerApplicationManager | 2.0.4
aws.greengrass.Nucleus | 2.5.3
aws.greengrass.TokenExchangeService | 2.0.3

I'm wondering if it is an awsiotsdk & awscrt version issue? This component installation just recently started failing to install.

This is the best output I could get - any debugging tips would be very helpful.

Thanks!
