Description

Hi Team,

I just upgraded Angular from v18 to v19 and I have trouble building all of the applications list in the Angular.json.

More specifically, I am getting the following error -

`✘ [ERROR] Cannot read properties of undefined (reading 'kind') [plugin angular-compiler]

node_modules/typescript/lib/typescript.js:30304:14:
  30304 │   return node.kind === 243 /* VariableStatement */;

Minimal Reproduction

  1. use ng update to update working Angular 18 app.
  2. run ng build id --watch --preserve-symlinks --output-hashing=all

    Hi Team,

    Does anyone have any one have any suggestions to try and track down this issue.

    This issue is obviously not happening to everyone.

    Our project has multiple apps in a single angular.json file.

    All apps except 1 cannot build due to this error. However 1 of them does build. The codebase is quite large and I am not sure where to look in order to isolate the issue.

    I have tried again with the latest angular and the problem still exists.

    Kind regards,
    Tarek

    It looks liks the issue orginiates from the new unused standalone import diagnostics.
    Until this is resolved, you can workaround an disable the diagnostic in your tsconfig with :

    {
  "angularCompilerOptions": {
    "extendedDiagnostics": {
      "checks": {
        "unusedStandaloneImports": "suppress"
      }
    }
  }
}

    Hi @JeanMeche,

    Many thanks for the tip. I have add the above to the tsconfig and I can now build all the projects.

    Kind Regards,
    Tarek
