Review comment:
@ferruzzi you get the error because this line doesn't do what you expect.
You expect it `"{{ dag_run.conf['resources_vpc_config'] }}"` to be the Json
define in the beginning of the file:
```
{
"subnetIds": ["subnet-12345ab", "subnet-67890cd"],
"endpointPublicAccess": true,
"endpointPrivateAccess": false
}
```
But this is not what is happening. The Jinja engine runs only in templated
fields of operators. It does not run in top level python code. So when you
execute `json.loads` you actually execute it on the string that you wrote.
If you will run in your python console :
`json.loads("{{ dag_run.conf['resources_vpc_config'] }}")`
You will see it will give you :
`json.decoder.JSONDecodeError: Expecting property name enclosed in double
quotes: line 1 column 2 (char 1)`
