Syntax for fileContents

[SirHamburger]

I try to add files via the fileContents.

My current template is the following:

    template {
      destination = "config/[[var "RETAILER_ID" .]].[[var "SYSTEM_ID" .]]/[[$settings.FILTER_CONFIG_FILE]]"
      data        = <<EOT
        [[ fileContents "../config-files/[[var "RETAILER_ID" .]].[[var "SYSTEM_ID" .]]/[[$settings.FILTER_CONFIG_FILE]]" ]]
        EOT
    }

And I get the following error:
Error: template: <file>:25: bad character U+0022 '"'

How can I add variables to the data block (with the new Syntax)?

I have found a hacky solution:

    template {
      destination = "config/[[var "RETAILER_ID" .]].[[var "SYSTEM_ID" .]]/[[$settings.FILTER_CONFIG_FILE]]"
      data        = <<EOT
[[$A:="../config-files/"]]
[[$B:=(var "RETAILER_ID" .)]]
[[$C:="."]]        
[[$D:=(var "SYSTEM_ID" .)]]
[[$E:="/"]]   
[[$F:=($settings.FILTER_CONFIG_FILE)]]
[[$concat:=(print $A $B $C $D $E $F) ]]
[[$concat  | fileContents]]
        EOT
    }
```
If anyone has a not so hacky solution, it is still appreciated.

Still not sure what the best possibility is but i've another one:

[[$baseSourcePath := list "../config-files/" (var "RETAILER_ID" .) "."  (var "SYSTEM_ID" .) | join "" ]]
[[$baseTargetPath := list "config/" (var "RETAILER_ID" .) "."  (var "SYSTEM_ID" .) | join "" ]]


...


    template {
      destination = "[[$baseTargetPath]]/[[$settings.FILTER_CONFIG_FILE]]"
      data        = <<EOT
    [[ list ($baseSourcePath) "/generated_filter_configuration/" ($settings.FILTER_CONFIG_FILE) | join "" | fileContents ]]
EOT
    }
