Hi <@U01RRDVSQ6T>,  You need to set the config value for the `subnet_cidr_blocks`` as follows:
`pulumi config set --path 'subnet_cidr_blocks[0]' 172.2.0.0/16`
This is because the code is written such that it is looking for a structured configuration setting so as to allow one to configure multiple subnet CIDRs.
(See <https://www.pulumi.com/docs/intro/concepts/config/#structured-configuration> for more info.)

Regardless, I’ll submit an update to the example so that the README provides this instruction.

Yes i try this at the moment it's work thank you so much for your response :slightly_smiling_face:
