so there is no way to get map object if its contains secret?

error: Error: Cannot call 'getOutputValue' if the referenced stack output is a secret. Use 'getOutput' instead.

Yes, just use getOutput instead. You'll get an Output<object>, and while normally doing things inside an apply can lead to preview issues, in the case of stack outputs the Output will always resolve so it's not in issue with those.

Thanks. i solved it with

getOutput().apply(x => x.something)

:)
