Webpack problem when deploying temporal worker

Community Support
1

Hi,

I’m currently evaluating Temporal for use with our platform. I’ve got a Temporal server running on our Kubernetes cluster and have a very simple typescript program (basically copying the hello world example) which I’d like to deploy to it. However when it’s deployed the following error is being generated:

Has anyone else seen this before or got any ideas ?

Thanks,

Did you use the same tsconfig.json and package.json from the hello world sample?
Can you share those?
Does this worker code run locally?

I haven’t seen this specific error before with our default setup.
It’d be great if you can provide a way to reproduce this, even if you just share your modified hello world project as-is.

I’ve now changed things so I’m using the same tsconfig/package.json. The code is the same as in the example. I seem to be having a problem with running locally at present so I can’t verify if this works. What I think I’ll try is to take your hello-world program as is and just add the extra bits to run this within our ci pipeline and see if that works ok.

Without more information about your setup I can’t assist further.
Why can’t you run things locally? Is this an environment issue?
Let me know if you come up with more information.
