   Results

    Current stack outputs (1):
        OUTPUT      VALUE
        someMapVar  {}

   Note This is empty due to the following reason.

   For something to be used as an output, it’s JSON.stringify’d. For maps, this is always {} IIRC. When printing to the console, node uses some special formatters which intercepts map types and does a pretty print on them - which is different to serializing to JSON.

   When writing to an output .. just use Object.fromEntries(map.entries()) This requires the ES2019 lib in the tsconfig to work

   we don't support the JS container objects Map and Set for serialization. Likely easier to use this than remembering to convert:

   public readonly somethingMapVar: Record<string, string>;

5. Destroy the stack

   pulumi stack destroy -y

6. Remove the stack. This will remove the Pulumi.dev.yaml file

   pulumi stack rm
