… intrinsic functions (#36157) ### Issue # (if applicable) Closes #36140 ### Reason for this change In #35838 we introduced typed relationships for L1 constructs. For properties with arrays, this incorrectly assumed that the value could not be a token. But it can and especially when using the `cloudformation-include` module. ### Description of changes Adds a check to ensure the value is not a Token, which cannot be used as an array, despite passing the type check. There are two places in `resolver-builder.ts` where we added a `.forEach()`. The first one is fixed in this PR, second location already has a check for a resolvable. Note we are only checking for a resolvable here, not if the value is actually an array. At some point this could extended to also check for an array, likely with some refactoring of the "in-place" mapping into a helper function (the currently generated code is very unreadable). For this PR I have chosen to do the minimal change. ### Describe any new or updated permissions being added n/a ### Description of how you validated changes Added a new unit test for this case. ### Checklist - [x] My code adheres to the [CONTRIBUTING GUIDE](https://github.com/aws/aws-cdk/blob/main/CONTRIBUTING.md) and [DESIGN GUIDELINES](https://github.com/aws/aws-cdk/blob/main/docs/DESIGN_GUIDELINES.md) ---- *By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license*
