Fails with eslint 8.40.0: TypeError: Cannot read properties of undefined (reading 'getAllComments')

[andersk]

Upgrading eslint from 8.39.0 to 8.40.0 (released an hour ago) causes xo to fail with this error.

❯ pnpm test

Discussing it here eslint/eslint#17167
In the meantime I downgraded to 8.39.0 again

I started experiencing this problem yesterday, downgrading xo to 0.53 didn't fix the issue

Appears the issue is actually with an older version of eslint-plugin-unicorn.

Apparently upgrading that plugin resolves the issue re: eslint/eslint#17167 (comment).

We may be able to resolve this issue by upgrading eslint-plugin-unicorn in xo to 47.0.0.

xo/package.json

Line 79 in 4bf9631

"eslint-plugin-unicorn": "^46.0.0",

Opened a bump PR up over here.

• Bump eslint-plugin-unicorn from 46.0.0 to 47.0.0 #720

[sindresorhus]

The issue was fixed in eslint-plugin-unicorn 46.0.1 (not 47): https://github.com/sindresorhus/eslint-plugin-unicorn/releases/tag/v46.0.1

Alright, let's do a bump to 46.0.1.

• Bump eslint-plugin-unicorn from 46.0.0 to 46.0.1 #723

Closing.

Solution

• update xo to at least v0.55.0
• or update eslint-plugin-unicorn to at least v46.0.1
