I added this file

“android”: {
“release”: {
“alias”: “johnS”,
“keystore”: “c:\my-release-key2.keystore”,
“keystoreType”: “”,
“password”: “”,
“storePassword”: “”

This is maybe a long overdue answer, but hopefully it will save somebody some time.
Here’s what you do:

  1. Right click on your “build.json” file
  2. “Open With”
  3. Select “Binary Editor”
  4. Remove the leading dots before the opening curly brace in your file.
  5. Save
  6. Build

Worked for me
