np prerelease error: Unexpected token u in JSON at position 0

[andreken]

Description

When I execute the command np and choose prerelease I receive the following error message: Unexpected token u in JSON at position 0 This happens when I have already created a prerelease and I'm trying to update it. The first time I published the prerelease (v5.0.0-0) it worked as expected.

package.json

{
  "version": "5.0.0-0",
  "engines": {
    "node": ">=14 <15",
    "npm": ">=6 <7"
  },
  ...
  "files": [
    "lib",
    "dist"
  ],
  "scripts": {
    "start": "rimraf .tmp/* && BABEL_ENV=development webpack-dev-server --config webpack.dev.config.js",
    "eslint": "eslint src/ --ext .js --ext .jsx",
    "eslint:fix": "eslint src/ --ext .js --ext .jsx --fix",
    "build:lib": "rimraf lib/* && BABEL_ENV=production babel src --out-dir lib",
    "build:dist": "rimraf dist/* && BABEL_ENV=production webpack --config webpack.prod.config.js",
    "prebuild": "npm run eslint",
    "build": "npm run build:lib && npm run build:dist",
    "deploy": "npm run build && np",
    "test": ""
  },
  "peerDependencies": {
   ...
  },
  "dependencies": {
  ...
  },
  "devDependencies": {
  ...
  }
}

Steps to reproduce

1. Move to a branch already published in prerelease (in my case different to master)
2. Run npm run deploy -- --any-branch
3. Select semver: prerelease (in my case 5.0.0-1)
4. Unexpected token u in JSON at position 0

Expected behavior

A new prerelease is created, with tag v5.0.0-1

Temporary workaround

Run npx np prerelease --any-branch --tag=beta

Environment

np - 7.6.0 Node.js - 14.18.1 npm - 6.14.15 Git - 2.30.1 OS - macOS 11.5.1

This is still an issue with [email protected] / Node.js v20.10.0 - can't do a pre-release:

? Select SemVer increment or specify new version prerelease     0.0.1-0

v20.10.0

Had to publish a patch release instead (0.0.1), which worked fine.
