const clientConfig = pulumi.output(azure_native.authorization.getClientConfig()); var azureSubscriptionId = clientConfig.apply(config => config.subscriptionId); produced this: Error: invocation of azure-native:authorization:getClientConfig returned an error: transport is closing at Object.callback (C:\source\repos\pulumi\DevOps.Infrastructure.Stacks\azure\net-core\web\node_modules\@pulumi\pulumi\runtime\invoke.js:139:33) What am I doing wrong?

I believe

azure_native.authorization.getClientConfig()

returns something like

Output<ClientConfig>

so if you pass it to

pulumi.output(...)

you're getting

Output<Output<ClientConfig>>

which isn't what you want. this should suffice:

var clientClient = azure_native.authorization.getClientConfig();
var subscriptionId = clientConfig.apply(c => c.subscriptionId);

Keep in mind that when you do this

subscriptionId

is still

Output<string>

so you can't just manipulate it like you would a string, it is still an output that needs to be asynchronously evaluated.

getting the string from the output<string> is what I am having trouble with. How would I go about that?

ok my first question is - what do you need to do with it? If you need it to just pass it to another resource, you don't need to get the string out - you can just pass it to the other resource as an Output. In fact this is what you are supposed to do. If you absolutely need to get the string out, then you need to await the Output. In typescript this means converting the Output to a Promise and awaiting that.

the issue is when I try to pass the value to another resource I get the error invocation of azure-native:authorization:getClientConfig returned an error: transport is closing

ah! ok so you do in fact want to

pulumi.output(...)

the promise that

getClientConfig()

returns. Then you can

var subscriptionId = clientConfig.apply(c => c.subscriptionId);

. Then you can pass that to your resource.

there are three lines of code: const clientConfig = pulumi.output(azure_native.authorization.getClientConfig()); var azureSubscriptionId = clientConfig.apply(config => config.subscriptionId); export const azid = "azure id: " + azureSubscriptionId;

export const azid = "azure id: " + azureSubscriptionId;

this line won't work because you can't concatenate types

string

and

Output<T>

. Instead you would want to:

export const azid = azureSubscriptionId.apply(x => "azure id: " + x);

the output is azure id: [object promise]

That means that

azureSubscriptionId

was not

Output<string>

it was

Output<Promise<T>>

correct, that is why the pulumi,.output was needed i thought

const clientConfig = azure_native.authorization.getClientConfig();

With this

clientConfig

should be

Promise<GetClientConfigResult>

const clientConfig = pulumi.output(azure_native.authorization.getClientConfig());

With this

clientConfig

should be

Output<GetClientConfigResult>

var azureSubscriptionId = clientConfig.apply(c => c.subscriptionId);

Now

azureSubscriptionId

should be

Output<string>

Which should allow you to:

export const azid = azureSubscriptionId.apply(x => "azure id: " + x);

and still have an

Output<string>

There had to have been a step that was missed if you still had a

Promise<T>

on the third line.

it seems that pulumi.output is actually creating UnwrappedObject<GetClientConfigResult>

ok, sorry. Must be quirk of typescript. I use dotnet primarily. I couldn't find one in the azure examples but I found an example using

pulumi.output(...)

here: https://github.com/pulumi/examples/blob/4529da55208d11bc708d88b8694f92f73455500d/linode-js-webserver/index.ts and we can see here that linode GetProfile also returns `Promise<TResult>`: https://www.pulumi.com/docs/reference/pkg/linode/getprofile/ And they are just accessing the properties on that directly after that. So maybe yours should only be 2 lines? Like this:

const clientConfig = pulumi.output(azure_native.authorization.getClientConfig());
export const azid = clientConfig.subscriptionId.apply(x => "azure id: " x);

that last example worked for me, thank you
