[BUG] the --long command is not giving expected results

[PhilipAbed]

Current Behavior:

im trying to run these flags:
C:\tests\projects\npm\npm7LsSS>npm ls --all --json --long
`npm ERR! Cannot destructure property 'dependencies' of 'node.package' as it is undefined.
{
"error": {
"code": null,
"summary": "Cannot destructure property 'dependencies' of 'node.package' as it is undefined.",
"detail": ""
}
}

npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\PhilipAbed\AppData\Local\npm-cache_logs\2021-02-18T15_01_37_387Z-debug.log`

1. the --long --json --all parameters were giving me "_deduped" field in the json result.. now it doesnt!
2. the error you see above is shown differently without the --long flag

Expected Behavior:

on the same project im running npm ls --all --json
without --long

im gettting tree + error stream:

npm ERR! code ELSPROBLEMS
npm ERR! missing: node-sass@^4.0.0, required by sass-loader@8.0.2
npm ERR! missing: sass@^1.3.0, required by sass-loader@8.0.2
{
  "error": {
    "code": "ELSPROBLEMS",
    "summary": "missing: node-sass@^4.0.0, required by sass-loader@8.0.2\r\nmissing: sass@^1.3.0, required by sass-loader@8.0.2",
    "detail": ""
  }

i want to be sure i'm understanding your issue correctly, is the problem only the missing _deduped field in the json result?

i believe that if you update to the latest npm 7 release (7.9.0 as of this moment) that the error you were getting should be fixed, but i want to make sure we're not missing anything here.

yes its those 2 issues, the error and the missing deduped... i dont care about the deduped anymore i worked around that manually using paths..
so if error is fixed thank you
