I need to capture the ip address associated with a network interface so I can build a configuration file that is stored in an s3 bucket. However using Pulumi.Output just gives me an Output object, i've tried using apply, concat and from_input methods but can't seem to get the actual ip address. `Output.all(net_interface.id).apply(lambda l: f"{l[0]}")`  works fine when used on the right hand side of a parameter assignment in the instance creation but not in a function that is called as the right hand side of the content parameter when creating the bucket object.

can you paste a larger code snippet here?

having created the network interfaces I do...

`network_interfaces = {}`
    `for (group_name, group_config, role_name, role_info) in process_nodes(cfg):`
        `for index, network_interface in enumerate(role_info["node_list"]):`
            `network_interfaces[f"{cfg.stack}-{group_name}-{role_name}-{index}"] = network_interface`

    `config = get_full_config(cfg)`
    `ghe_ha_config_bucket_object = aws.s3.BucketObject(`
        `"ghe-ha-config-bucket-object",`
        `bucket=config_bucket.id,`
        `content=Output.from_input(network_interfaces).apply(update_config(config, network_interfaces)),`
        `opts=pulumi.ResourceOptions(depends_on=network_interfaces.values()),`
    `)`

`def update_config(config: str, network_interfaces):`
    `for name, network_interface in network_interfaces.items():`
        `value = network_interface.private_ips[0]`
        `config = config.replace(f"{name}-ipv4_address", value, 1)`
    `print(f"{get_caller()} - config: {config}")`

To update the configuration data replacing &lt;name&gt;-ipv4_address with the private ip address of the correct network interface
