Hi, wondering how I could stop pulumi preview or update when error occurred and handle exceptions however I want. Right now I just throw an exception, it does the work but I see:

error: Program failed with an unhandled exception:

, instead I want a short and clear message.

I thought we already had an issue about this, but I can only find https://github.com/pulumi/pulumi/issues/3364 which I don't think is exactly what your asking for. It's an interesting idea though.

Not quite. My scenario is the following. I’m developing a component that could build Docker images from remote repositories, to do that I should clone contents. But there could be some errors, like repo doesn’t exist, you lack permissions to access it etc. So right now I’m doing it like:

pulumi.error('repo not found')
raise NameError("Repository {url} doesn't exist or you lack permissions.')

it stops the execution and shows the errors but says it has unhandled exceptions. And I see 4 errors instead of one.

Gimme a minute, there might be a way to do this I'll go have a quick code splunk. If not this sounds like a reasonable feature request to make on github.

Thanks, done: https://github.com/pulumi/pulumi/issues/10154

Thanks! We'll take a look into this
