Fix yaml bug resulting in TypeError: Cannot read properties of undefined

[viveklak]

Proposed changes

Fixes #2038 for typescript.
Fixes #1987 for python.

As discussed on the issue, calling an invoke on an unconfigured provider results in the invoke never reaching the provider. This fixes a halting error here but it will not return the correct preview if things like kubeconfig are missing in the provider.

@LucasBrazi06 Could you please open a new issue for that? I want to make sure we don't lose track of this.
