Summary
The user is facing an error when using the ListTransformer with a list of DataClasses in a task involving an Agent. They are unsure if the ListTransformer can be modified to handle this situation or if a specific TypeTransformer for list[Foo] is necessary. They mention that lists of DataClasses work fine as workflow arguments in subworkflows. The user provides code snippets for context and expresses confusion about the source of the error, initially thinking it was related to the task but later realizing it occurs earlier in the process. They seek input from others for clarification.
