autopilot:deploy errors out with "Cannot read property 'startsWith' of undefined"

First of all great work with the autopilot plugin, I find it already very useful doing my first steps with Twilio Autopilot!

I'm running into an issue where autopilot:deploy gives me consistently a Cannot read property 'startsWith' of undefined.

The redacted (confidential information removed) output of twilio autopilot:deploy -l debug --override-existing-project --target function is:

What I have tried so far:

Running only twilio autopilot:deploy -l debug --override-existing-project --target model, works :tada:
Doing an twilio autopilot:init specifying account sid and auth token via -u and --auth-token, didn't change anything
Marking my current Twilio profile as active, didn't change anything

I'm a bit lost, what could be the issue? It looks like my account sid can't be found and as a matter of fact it's not in the config but this is just after a fresh twilio autopilot:init.
