Using Pulumi with Typescript, if I make a typo in some variable name or make some silly syntax mistake I get this obscure error message (regardless of what the problem is) instead of the expected error message pointing to the actual error:

TypeError: Cannot convert object to primitive value
        at process.uncaughtHandler (/home/ubuntu/infra/node_modules/@pulumi/cmd/run/run.ts:305:65)
        at process.emit (node:events:531:35)
        at process.emit (/home/ubuntu/infra/node_modules/source-map-support/source-map-support.js:516:21)
        at emit (node:internal/process/promises:150:20)
        at processPromiseRejections (node:internal/process/promises:284:27)
        at processTicksAndRejections (node:internal/process/task_queues:96:32)

any ideas ?

👋 can you provide a short snippet/example of a typo you're doing? TS is usually pretty helpful e.g. I misspell my variable `bucket`:

index.ts(9,27): error TS2552: Cannot find name 'bucketr'. Did you mean 'bucket'?

I have the same issue, it's been happening for a while. I'm using ESM modules to get top-level await (I have this config since 3 years):

# Pulumi.yaml
name: proj
description: something
runtime:
  name: nodejs
  options:
    typescript: true
    # See <https://github.com/TypeStrong/ts-node/issues/1007>
    nodeargs: "--loader ts-node/esm --no-warnings"

@bland-processor-73185 are you saying this is ESM-specific or?

Indeed this seems to be ESM-specific A simple

index.ts

containing just

failll

causes:
