ns migrate (to 8) failing at Android step

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 8.0.2
• Cross-platform modules:
• Android Runtime: 7.0.1
• iOS Runtime: 6.5.4
• XCode Version: 12.5.1
• Plugin(s): none

Describe the bug

spawn: npm "install" "--legacy-peer-deps" "tns-android@8.0.0" "--silent" "--dev" "--save-dev" "--save-exact"
Will send the following information to Google Analytics: {
  type: 'googleAnalyticsData',
  category: 'CLI',
  googleAnalyticsDataType: 'event',
  action: 'Performance',
  label: 'PackageManager__install',
  customDimensions: { cd2: 'Angular', cd9: 'false', cd5: 'CLI' },
  value: 10877
}
Error: Command npm failed with exit code 1
    at ChildProcess.<anonymous> (/usr/local/lib/node_modules/nativescript/lib/common/child-process.js:143:36)
    at ChildProcess.emit (events.js:315:20)
    at maybeClose (internal/child_process.js:1048:16)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:288:5)

To Reproduce

ns migrate --log trace

Expected behavior
Succesful migration

Start by reproducing ns migrate --log trace with the reported CLI and runtime versions. Inspect nativescript/lib/common/child-process.js where the npm process failure is reported, then identify what causes the Android installation to exit with code 1; done means the migration completes successfully.
