[SOLVED] IBM Cloud Developer Tool: idt build/bx dev build causing error (OCI runtime exec failed ...)

I'm getting an error running bx dev build in my Node.js project folder, specifically:

[hafiz@Ubuntu ~/FSFTM/code/TaskListApp] $ sudo bx dev build
Getting service credentials for the project.

Dumping output from the command: 
OCI runtime exec failed: exec failed: container_linux.go:295: starting container process caused "process_linux.go:86: executing setns process caused \"exit status 22\"": unknown

Right before these, I ran bx login --sso and bx target --cf. Can't tell what the issue is exactly, I suspect it's something to do with Docker. I'm running this on an Ubuntu 16.04. Installed idt by running curl -sL https://ibm.biz/idt-installer | bash. Here's the version of bx:

[hafiz@Ubuntu ~/FSFTM/code/TaskListApp] $ bx -v
bx version 0.6.4+41cb1aa-2017-12-19T03:46:07+00:00

Not too sure what else I should include in this, I'm kinda stumped. The project builds fine by running npm install, npm run build and npm run start. I'd give additional info if I knew what would be useful! Anyone with a clue what the error really means or if I missed something?

As requested by joe, here's the trace:
