Invalid rule configurations compiled by "eslint --print-config" on eslint-config-airbnb-typescript

[U-4-E-A]

I recently ran eslint --print-config example.js > output.json on my eslint config extending from airbnb-typescript-prettier and some of the rules extracted from packages such as eslint-config-airbnb-base are invalid. Example: -

"import/no-cycle": [
	"error",
	{
		"maxDepth": null
	}
]

Results in the error: -

Error: .eslintrc.js:
Configuration for rule "import/no-cycle" is invalid:
Value null should be integer.

There are a number of other rules that have invalid config: -

eslint-config-airbnb-typescript and airbnb-typescript-prettier are different packages that we do not maintain or necessarily endorse. We provide Infinity as the maxDepth value, which is valid: https://github.com/airbnb/javascript/blob/master/packages/eslint-config-airbnb-base/rules/imports.js#L236

Perhaps one of these packages is processing our config incorrectly?

[waissbluth]

@U-4-E-A did you get to the bottom of this? we are using eslint-config-airbnb-base directly and this suddenly started happening

[mjeffryes]

I also ran into this this morning after running eslint.js --init to setup a new package.

[ljharb]

Can both of you perhaps file a new issue and provide a bit more information, including your configs?

[mding5692]

Having issues too with this

eslint 7.3.0 was released only an hour ago. It seems to contain something that causes this error.

I fixed this by re-installing eslint 7.2.0

[eistrati]

Same here. Started to appear this morning. Looks like something related to this package: https://www.npmjs.com/package/eslint ... 7.3.0 • Public • Published an hour ago.

@eistrati
The reason is here: https://github.com/eslint/eslint/blob/master/lib/cli-engine/config-array-factory.js#L725

Related PR: eslint/eslint#13034

Bug created: eslint/eslint#13427

[ljharb]

This is indeed a bug in eslint v7.3.0; downgrade to v7.2 for now.
