does anyone have any experience importing json files in pulumi projects? I’m using AJV to do some config validation and have the following code:

import * as pulumi from '@pulumi/pulumi';
import Ajv, { JTDDataType } from 'ajv/dist/jtd';
import repoConfigSchema from './config-schema.json';

// ...

however when running the program with

pulumi up

i get the following error:

pulumi:pulumi:Stack (gh-repos-main):
    error: Running program '<redacted>/src' failed with an unhandled exception:
    TSError: ⨯ Unable to compile TypeScript:
    config.ts(3,30): error TS2732: Cannot find module './config-schema.json'. Consider using '--resolveJsonModule' to import module with '.json' extension.

        at require (internal/modules/cjs/helpers.js:92:18)

but i have enabled

resolveJsonModule

in my tsconfig:

{
  "$schema": "<https://json.schemastore.org/tsconfig>",
  "display": "Node 14",
  "compilerOptions": {
    "target": "es2020",
    "lib": [
      "es2020"
    ],
    "module": "commonjs",
    "outDir": "dist/",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true,
    "resolveJsonModule": true
  },
  "include": [
    "src/**/*.ts",
    "src/**/*.json"
  ]
}

any ideas what I’m missing?

You might need

"moduleResolution": "node",

?

that didn't help, but i found the problem is related to me changing the

main

property in

Pulumi.yaml

. it seems to mess with module resolution in certain cases, this being one of them
