Trying to get an azure function app running and I keep getting this error:
Copy code
Error: Invoke of 'azure:storage/getAccountBlobContainerSAS:getAccountBlobContainerSAS' failed: "container_name": required field is not set ()

but those resources seem to be validly defined in my index.ts file:
Copy code
// The container to put our files into
const container = new azure.storage.Container("files", {
    
    storageAccountName: storageAccount.name,
    containerAccessType: "private",
});

// <http://ASP.NET|ASP.NET> deployment package
const blob = new azure.storage.Blob("zip", {
    storageAccountName: storageAccount.name,
    storageContainerName: container.name,
    type: "Block",
    source: new pulumi.asset.FileArchive("<https://github.com/mapped/connector-functions/suites/1471048737/artifacts/25311357>"),
});
anyone have any ideas what's going on?

Is there more to your code? The error message refers to 
azure:storage/getAccountBlobContainerSAS:getAccountBlobContainerSAS
which is a lookup function, but isn't present in the code you shared.
c
yeah, of course. that's referring to something in a bunch of the node_modules that are automatically installed on a new pulumi project. Here's the full stacktrace.

Sorry, I meant is there more code to your Pulumi application?
c
oh yeah, of course. hang on, I'll drop it here. thanks for taking some time with this 🙂

I know the function itself is working, currently running in some docker setup that predates me at this company. working on getting it migrated to pulumi administered microservices. If I point to a different, "hello world" app it works fine, but as soon as I point it to this function instead, it fails like this
g
Is that the entirety of the code in your Pulumi application? Given the error, message I would expect to see a call to 
getAccountBlobContainerSAS
- https://www.pulumi.com/docs/reference/pkg/azure/storage/getaccountblobcontainersas/#getaccountblobcontainersas.
c
yeah, 100% of our code is in the pulumi app I copied above. that 
getAccountBlobContainerSAS
function lives in the node_modules installed by default with pulumi new. Which is part of why this has been so difficult to troubleshoot
g
Do you get this during 
preview
or only on an 
up
?
Your code previews successfully for me.
Ah... I think I see what's happening.
Still looking into this. Thanks for your patience.
Ok, unfortunately I think 
pulumi.asset.RemoteArchive
is failing silently in this case because it is expecting a .tar, .tar.gz, or .zip file extension which the URL you're using does not have. Also, I suspect you might hit another issue where the URL you're using seems to require an authenticated user as it returns a 404 and it looks like the 
pulumi.asset.RemoteArchive
also isn't handling 404's correctly.
So... the fix would be to use a URL that ends in .zip (or other archive extension) and make sure that it's reachable - so likely would need a signed URL or other means to authenticate.
And I'll open an issue to improve the error handling and messaging in these scenarios/
c
@gentle-diamond-70147 thanks a ton. I continued tinkering with it last night, got it working this morning. I was definitely doing it wrong. Wrote it out this way and it works fine. I think the main issue with the previous method was that the errors were so obscure I couldn't figure out how to troubleshoot it. Here's the version that worked, for reference.
Copy code
//Use this to create a function app from a remote archive
const app = new azure.appservice.FunctionApp("connectorFunctions", {
    resourceGroupName: resourceGroup.name,
    appServicePlanId:plan.id,
    storageAccountName: account.name,
    storageAccountAccessKey: account.primaryAccessKey,
    appSettings: { 
        runtime: "dotnet",
        websiteRunFromPackage:  "<https://github.com/mapped/connector-functions/suites/1483831234/artifacts/25707154>"
    }
});
g
Glad you got it fixed. Agreed the errors were very obscure.
I'm not familiar with the 
websiteRunFromPackage
option. I'm curious... how does azure authenticate to download the private artifact?
c
getting the authentication sorted was key. You have to run
Copy code
pulumi config set github:token <token> --secret
g
Interesting. Learned something new today, thanks!
