Apparently the issue is still present while migrating a Nx 17 project into a Nx 19

@Coly010 can you please verify this again?

after some debugging, I guess the problem is on the schematic of the migration:

nx/packages/angular/src/migrations/update-17-1-0/browser-target-to-build-target.ts

Line 70 in 3a2e8d4

if (config.browserTarget) {

this diff should change it:

function updateConfig(config: {
  browserTarget?: string;
  buildTarget?: string;
}): void {
-  if (config.browserTarget) {
+ if (config && config.browserTarget) {
    config.buildTarget ??= config.browserTarget;
    delete config.browserTarget;
  }
}

after that, my code was able to migrate successfully to 19:
