SDK Build error - Migrating from Wasp 0.16.0 to 0.20.0

General Wasp

Hi Wasp team! I'm trying to migrate from Wasp 0.16 to 0.20 and hitting an SDK build error.

Environment:

Wasp 0.20.0
Node.js 22.21.1
macOS

Error:
SDK build failed with exit code: 2
error TS2307: Cannot find module 'wasp/src/features/...' or its corresponding type declarations.

The SDK generates imports like:
import { generateMessage } from 'wasp/src/features/generate-message/server/actions'

But TypeScript can't resolve wasp/src/* during compilation because:

package.json exports map "./src/": "./dist/src/.js"
During tsc, the dist/ folder doesn't exist yet → chicken-and-egg problem

Workaround found:
Adding this to .wasp/out/sdk/wasp/tsconfig.json fixes the build:
"baseUrl": ".",
"paths": {
"wasp/src/": ["./src/"]
}

Problem: This fix only works locally. On deployment (wasp build), the SDK is regenerated without the path mapping, so production builds will fail.

My project structure: Feature-first architecture with actions/queries in src/features/*/server/actions/ (standard @src/features/... imports in main.wasp).

Is this a known issue? Any workaround for production deployments?

Thanks!
