A Reproduction of issue 465 in AppSignal Webpack
npm install- ensure line 11 is uncommented in
app.component.ts npm run build
Issue:
The error you get is:
An unhandled exception occurred: ENOENT: no such file or directory, unlink main.js.map
Note there is no mention why this file does not exist (the actual reason is that the TS compile has failed and it did not produce any .js or .map files).
To fix: Navigate to node_modules/@appsignal/webpack/dist/cjs/index.js and on line 189 add a .catch(() => {}) to the .unlink() call and save.
Run npm run build again.
You will see the actual typescript error printed out as expected:
Error: src/app/app.component.ts:11:3 - error TS2322: Type 'string' is not assignable to type 'boolean'.
11 brokenValue: boolean = 'string';
