Migration from dt-app 0.148.1 to dt-app 1.0.2 error (new project structure)

Hello,

I've recently made the dependencies update of my custom app, with in it the new major version of dt-app. In the new version, there is a new project structure files, so I followed the migration guide of the wiki : https://developer.dynatrace.com/quickstart/app-toolkit/#migrating-from-v0x-to-v1x

When I try to lunch my development app, i've got the error that I have the wrong files structure, but I don't see the problem. I tried to add empty `documents` and `actions` folders, or add a README.md in it but I still have this error :

✖ Building ui... Invalid project structure detected Your project uses an outdated file structure that is not supported in dt-app v1.0. To ensure compatibility and avoid build issues, please update your project structure. Required Changes: 1. Configure sourceRoot in app.config.json: • Set "build.sourceRoot" to your desired source directory (default: "./") • Example: "build": { "sourceRoot": "src" } 2. Organize your code using the standardized structure: <sourceRoot>/ ├── ui/ ← UI components and main.tsx │ ├── main.tsx │ └── tsconfig.json ├── api/ ← App functions (*.function.ts) ├── actions/ ← Workflow actions (*.action.ts) ├── settings/ ← Settings widgets and schemas └── documents/ ← Document files Thank you for your support!

Thanks for your help by advance,

Kind regards,

Evan

PS : I've also tried to add the suggested build.sourceRoot option in my app.config.json but doesn't work

"build": { "sourceRoot": "./" }

Hi there,

the solution to this problem is to remove every single "src" in your imports in the whole project. If you have an error with a src/ import in, it would return this error (instead of returning import error I guess)
