yes I think postgres version and lambda runtime version need updating there

I tried updating them in the

<http://variables.tf|variables.tf>

files, but the terraform plan + apply appeared to be ignoring the variables that I had in there...for example lambda says to use "python3.12" but if you look at the error I get, it indicates that the lambda is trying to use "python3.7" 😕 The same thing happened with postgres. I'm a terraform noob so I could definitely be doing something wrong though 😅

This is because the example in metaflow.tf uses external modules and these values are coming from those. You have two choices: 1. change 0.10.0 to 0.12.0 for all modules 2. replace the

source

directive with

"../../modules/$module_name"

(replace

$module_name

with the given module) so it will use the checked out modules from the same repo Do a

terraform init

after you do this.
