Hi all - newish to pulumi. I created a Dynamic Resource Provider in python that has an output of

new_tags: Output[List[str]]

. The code seems to be working, I can see the resource in preview and code being executed but having a hard time actually getting the output list. Trying to follow along from documentation but

new_tags.apply(lambda x: f"{x[0]}")

or even

new_tags.apply(lambda x: print(x)

still errors out with

tags: Calling __str__ on an Output[T] is not supported.

The output you’re getting suggests that you may be dealing with an

Output[list[Output[str]]

instead of just an

Output[list[str]]

? If that’s the case, further expanding with another apply, or (if it my be a mix on inputs and outputs) defining a function such as:

def print_output_list(output_list: list[Input[str]]):
   as_outputs = [ Output.from_input(x) for x in output_list ]
   Output.all(*as_outputs).apply(print)

And then calling

new_tags.apply(print_output_list)

could help
