HI! i think there's a problem with pulumi-python v2.21

File "/usr/local/lib/python3.7/site-packages/pulumi/runtime/resource.py", line 358, in do_register

        raise ValueError("Output.all() was supplied no inputs")
    ValueError: Output.all() was supplied no inputs

It doesn't happen with pulumi==2.20.0 (tested with pulumi cli 2.14 and 2.21)

Hi @creamy-knife-53051 I am wondering if this is due to this behaviour change . https://github.com/pulumi/pulumi/pull/6269

I Saw that.. but in my piece of code i don't use output.all... I have to change something in my code ?

you don't use Output.all anywhere?

define anywhere 😄 In that particular stack, i refer only to output of another stack eg:

network_interfaces=[{
                                          "accessConfig": [{}],
                                          "network": parentStack.get_output('vpc_id'),
                                          "subnetwork": parentStack.get_output('subnet_id'),
                                      }],

ok, this feels lile a bug then - can you open an issue on pulumi/pulumi describing this so that one of the team can look at this?

yup!

thank you!

Thank you so much

Thanks for reporting this! Seems like my output.all change inadvertently caused this. Will look into it first thing today.

thankyou
