Pulumi Community

I don’t have a real answer for you.
But I copied your security group declaration and was able to `pulumi up` without the error.
So it seems it may be related to your environment?

<@U018R959Y9F> I would suggest it's down to the version of pulumi-aws you are using

<@U01BSQWRZFA> I would try that again. Thank you Mitch

<@UHTP242EB> Which pulumi version should i run to?
The current version. i am running is 2.12.1
I saw the warning while running pulumi  `A new version of Pulumi is available. To upgrade from version '2.12.1' to '2.14.0'`

Pulumi-aws package is the potential issue here - what version are you running?

The current version of pulumi-aws :3.13.0

Unless you’ve updated the requirements.txt and not actually ran a pip install to get the new packages 

I have installed all requirements as well. But still let me follow up and try installing again from scratch.
