My build section looks like

  "build": {
    "appId": "com.sandi.rsmanager",
    "win": {
     "target": "NSIS"
    }
  },

It's similar to #2660 but i am on version 20.19.2

[sandiz]

the same json works perfectly when i am building for mac though

[nosferatu500]

Version 20.28.1
I get #2660 error in random time for same builds.

For example: I build project with webpack & electron-updater. Build it 7 times. And I get this error 4 times. How I can solve it?

PS: I . don't change code for before each build.

I am experiencing a similar problem. I get
SyntaxError: Unexpected token < in JSON at position 1121 at JSON.parse (<anonymous>) when running electron-builder.

It appears that <anonymous> is somehow getting pased in pretty early. The bottom of the entire callstack shows at then (<project path here>/node_modules/electron-builder/src/cli/cli.ts:46:19)

same error here but with Mac! if my dependencies contains "@angular/pwa": "^0.12.3", (or other versions) i got error SyntaxError: Unexpected token < in JSON at position 1121 at JSON.parse

Its related to the @schematics/angular verison required within @angular/pwa.
On older versions of schematics some template files where suffixed with .json which made electron-builder trying to parse them and treat them like valid JSON.

While actually it was not valid JSON. Since @schematics/angular >= 7.3.0 they suffixed these files with .template and the error is gone.

See https://github.com/angular/angular-cli/commit/36eba0c9fcf17305a7ef99096c860ad271c5aaf7#diff-84ab480b30e45c756807451b0b4411e1
