hm i dont think there’s a problem with this approach. possible issue is that addtOrigins is optional which you cant spread if it’s undefined, you can use a default like `addtOrigins: &lt;type&gt; = []`so its an array even if nothing is passed in

oh jk you have the default there. what’s the TS error you’re getting

`Type 'Input&lt;Input&lt;DistributionOrigin&gt;[]&gt;' must have a '[Symbol.iterator]()' method that returns an iterator.`

try this
```    origins: pulumi
      .output(addtOrigins)
      .apply((addtOrigins) =&gt; [...addtOrigins, {...}]),```

actually this is the right way:

replace the type of `addtOrigins` with the real object type (not wrapped in pulumi.Input):

`aws.types.input.cloudfront.DistributionOrigin[];`

i've done that before i just could not quite remember how i had done it :slightly_smiling_face:
