How to Define a List Input in Extension v2 Activation Schema?

[Eyad]

Hi all,
I'm developing a custom extension using Extension Framework v2, and I want to allow users to input a list (e.g., a list of strings) via the UI configuration. I tried using the following schema:

But I received the error:

Schema validation failed with Exception: 'Non-collection property cannot be of type 'list' or 'set''

Could you please clarify:

1. Is it possible to define a list (or array) input in the activation schema for a Dynatrace extension?

2. If not, what is the recommended workaround for passing multiple values from the UI to the extension (e.g., comma-separated string)?

3. Is there any support for more complex input types (like tables or groups) in the activation.schema.json?

Thanks in advance!
