Hej everyone! Using Typescript, how would I go about using pulumi-specific types in Lambda functions? Naively importing them in the same way you would with custom defined types results in the

Cannot find module '@pulumi/pulumi/runtime/index.js'

error, I guess because

@pulumi/...

packages are not included in the Lambda. Any way around this?

Short of installing Pulumi in the lambda, no. What types do you want to use in a lambda? There may be a different way to achieve your goals.

I'm passing a TopicEvent to a Lambda function to process it further. There are workarounds (

JSON.stringify()

e.g.), but it'd be nice to keep the proper types, if at all possible

The event arrives in the lambda as a JSON payload, I believe? There's a class in the AWS SDK you could use, but since it's not a Pulumi object, there's no need to bring Pulumi into the equation, I think?

Copying the code is what I've went with for now, but thanks for the hint, will look for the SDK versions : )

If you are just using the types, this should work just fine, as they are only used at TypeScript build time. Can you perhaps share a snippet of the code you are using inside your CallbackFunction, and how you are using

TopicEvent

?

Checked again and you are right! The issue was passing a parameter with

pulumi.Config().require()

without storing it as an intermediary variable.
