this error is not really helpful :

error: Error: Invoke of 'gcp:serviceAccount/getAccount:getAccount' failed: undefined (undefined)
        at Object.<anonymous> ([...]/node_modules/@pulumi/pulumi/runtime/invoke.js:82:23)
        at Generator.next (<anonymous>)
        at fulfilled ([...]/node_modules/@pulumi/pulumi/runtime/invoke.js:17:58)

coming from :

const account = gcp.serviceAccount.getAccount({ accountId: '[account_id]' })

I followed the function declaration from

getAccount.d.ts

, I’m missing something here
