I do believe it should be `args=aws.efs.FileSystemArgs()` . Maybe you were confused by square brackets from docs in
```Optional[FileSystemArgs] ```
but they just denotes the type of the argument for the optional argument.

Also you are using “efs_filesystem” for the first positions parameter `resource_name` and then use it again as a named parameter

<@U02PSPSD16Y> I have tried the code you showed me, nbut that didn’t work for me earlier.

<@UCWG26BH7> Can you please give an idea?

I'm always happy to help where I can, but please remember this is community support

could you give more information? wht error are you getting?

```foo = aws.efs.FileSystem(
    "efs_filesystem", 
    resource_name="efs",
    args=[aws.efs.FileSystemArgs()]
})```
When i try to put `args=[aws.efs.FileSystemArgs()]`  that format doesn’t work with it.

I am trying to put these parameters in efs api

shouldn't it be:
```foo = aws.efs.FileSystem(
    "efs_filesystem", 
    resource_name="efs",
    args=aws.efs.FileSystemArgs()
})```

what do you mean "it didn't work" ? can you elaborate on what that means?

When i am trying to add the function, that doesn’t even list out.

that appears to be an issue for your autocompletion, it works fine for me

update your global `pulumi_aws` to the latest version
