We are using pulumi with typescript and a pulumi yaml config file. We have included “enableIstio”: false using “pulumi config set enableIstio false”. If we use let blabla = config.getBoolean(“enableIstio”) || true it always results in true so I assume we cannot use this example? I know that typescript defines it as such. For let blabla = config.getNumber(“somenumber”) || 20 is working correctly except in the case where your number is a 0 (=false). A bit of a gotcha as a lot of these code examples use || and not ??

have you instantiated the config? e.g.

const x = new pulumi.Config();

Hi,Paul. Yes we use

const config = new pulumi.Config(“pulumi”)

Drop the Pulumi part and try it - I don’t believe you need that

if Indo a console.log it returns the correct value so it reads the config directly

Yes - you are right about the gotcha here (if you see any Pulumi example code that has a bug due to this let us know). The

??

operator was just added to TypeScript 2 months ago, and is not widely known syntax yet - which is the primary reason it’s not used in examples yet. It is indeed closer to the desired semantics for this use case.
