Addon Validation Error: value equal null

[lidel]

Information

Tried to upload fennec version for android:
ipfs_companion_beta_aeecbb5_-2.8.4.824_fennec.zip

Got error without any explanation:

• This error occurred during the submission of a new version of an existing add-on
• Add-on is unlisted (self-hosted beta channel)
• The URL where you submitted the add-on: https://addons.mozilla.org/en-US/developers/addon/9d155c1c2b6147c39860/versions/submit/
• The approximate time submitted the add-on, with timezone: 2019-09-19 13:30 CEST

Bug?

I think it is because of "incognito": null in manifest.json. Addon loads fine into Firefox, however addons-linter does not support null keys and returns an error:

$ web-ext lint
Applying config files: ./package.json, ./web-ext-config.js

Solution?

I think null values should be allowed, it is a valid JSON.

Should null be accepted ?
According to this incognito is an enum of ["spanning", "split", "not allowed"]
https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/incognito

While looking this up i found another potential bug, the MDN docs say that it should accept ["spanning", "split", "not allowed"] but the current validation accepts only ["spanning", "not allowed"]

Edit: my bad "split" isn't supported in firefox 😭

@Rob--W what do you think we should do here? According to the comment above, null isn't valid.

@willdurand I just tried to reproduce this locally and I got a nicer validation result with incognito set to null:

 ./bin/addons-linter tmp/test-incognito-null
Validation Summary:

errors          2
notices         0
warnings        0

ERRORS:

Code                     Message                                  Description                                                   File            Line   Column
MANIFEST_FIELD_INVALID   "/incognito" should be string            See https://mzl.la/1ZOhoEN (MDN Docs) for more information.   manifest.json
JSON_INVALID             "/incognito" should be equal to one of   Your JSON file could not be parsed.
                         the allowed values

This validation result seems nice enough and so if the original error can't be reproduced anymore I would keep this behavior.

@rpl That warning looks good enough to me.
