X-Post from a thread in #azure (not Azure related): I am passing an `Output<string>`to a module in my TS stack. That module takes that as an argument. I then use that argument as input to a resource and things fail with "Calling [toString] on an [Output<T>] is not supported".

...
export function scanApp(resourceGroupName: Output<string>,...): {

...
const appName = pulumi.interpolate`argos-${resourceGroupName}`;
const prefix = `${appName}-${stack}`;
new appservice.Plan(appServicePlanName, {
      resourceGroupName: resourceGroupName,
      name: prefix
...
}

I guess it fails on

prefix

? How do I do this?

prefix also needs to use

pulumi.interpolate

yeah, I found that, but I also realised that

appServicePlanName

a bit higher up also uses

appName

which is apparently not supported. The resource name can't use

pulumi.interpolate

yes, resource names must be known ahead of time so the stack can be built

hmm, so best to not make them depend on anything environment specific then
