How does one assign a stack output to an

Output<string>

variable? The docs show this example:

const ip: Output<string> = infra.getOutput("privateIp");

But I get a compilation error when I try something similar, since we can't assign Output<any> to Output<string>.

TSError: ⨯ Unable to compile TypeScript:
    index.ts(28,9): error TS2322: Type 'Output<any>' is not assignable to type 'Output<string>'.
      Type 'OutputInstance<any>' is not assignable to type 'Output<string>'.
        Property 'length' is missing in type 'OutputInstance<any>' but required in type 'LiftedObject<String, NonFunctionPropertyNames<String>>'.

What's the correct solution here? Thanks

getOutput("someKey")

return type is

pulumi.Output<any>

not

pulumi.Output<string>

. You could leave the variable untyped

const ip = ...

or also use an apply statement to provide the string type.

getOutput("someKey").apply(s => <string>s);

So this is indeed a documentation bug?

By the looks of it, yeah.

thx for confirming
