I'm creating a cloudfront distribution with attached lambda functions ("Lambda@Edge"). The ARN and Version properties on my lambda functions (`aws.lambda.CallbackFunction`) are resolving to `undefined` inside `apply` . Why would that be? (thread)

Relevant code, creating a lambda &amp; associating it with CloudFront:

```directoryRetryHandler = new aws.lambda.CallbackFunction(`...`, {
  ...
}),

docsDistribution = new aws.cloudfront.Distribution(`...`, {
  defaultCacheBehavior: {
    ...
    lambdaFunctionAssociations: [{
      eventType: "origin-response",
      lambdaArn: pulumi.interpolate`${directoryRetryHandler.arn}:${directoryRetryHandler.version}`,
    }]
  }
}),```
When I try to bring the stack up, AWS complains:

```error creating CloudFront Distribution: InvalidLambdaFunctionAssociation: Invalid function ARN: undefined:undefined```

This same code previously worked with the CLI ...

I believe you are hitting this known issue: <https://github.com/pulumi/pulumi/issues/5578>

The workaround is setting the `workdir`:
