Unexpected top-level property "name" in 5.x.x versions

[DenisValcke]

Hi

When bumping my ESLint dependencies (including this one) to the latest version, I get this error:

 NX   ESLint configuration in apps/v-loket-products-e2e/.eslintrc.json » plugin:cypress/recommended is invalid:

        - Unexpected top-level property "name".

Referenced from: <path-to>/.eslintrc.json

The same error seems to have popped up in eslint-config-prettier:
prettier/eslint-config-prettier#308

My dependency versions, just for extra context:

"cypress": "15.5.0",
"cypress-image-snapshot": "4.0.1",
"cypress-plugin-snapshots": "1.4.4",
"cypress-wait-until": "3.0.2",
"eslint": "9.38.0",
"eslint-config-airbnb": "19.0.4",
"eslint-config-prettier": "10.1.8",
"eslint-import-resolver-exports": "1.0.0-beta.5",
"eslint-import-resolver-typescript": "4.4.4",
"eslint-plugin-cypress": "5.2.0",
"eslint-plugin-import": "2.32.0",
"eslint-plugin-import-order-autofix": "0.8.3",
"eslint-plugin-prettier": "5.5.4",
"eslint-plugin-tsdoc": "0.4.0",
"eslint-plugin-unused-imports": "4.3.0",

I was on 4.2.1 and I can bump to 4.3.0 without problems, but when I try any of the 5.x.x versions the problem starts popping up.

Thanks for looking into it.

You are seeing an error message:

NX ESLint configuration in apps/v-loket-products-e2e/.eslintrc.json » plugin:cypress/recommended is invalid:

    - Unexpected top-level property "name".

with the latest version eslint-plugin-cypress@5.2.0. Using eslint-plugin-cypress@4.3.0 you see no error.

Explanation & Background

This is an unsupported configuration for eslint-plugin-cypress >=5.0.0:

• .eslintrc.json belongs to the deprecated eslintrc configuration file format
• The deprecation by ESLint was announced in Flat config rollout plans in October 2023 and became implemented with the release of ESLint 9.0.0 in October 2024.
• The eslint-plugin-cypress plugin retained support for the legacy configuration format until the release of eslint-plugin-cypress@5.0.0 on May 29, 2025.

The latest ESLint 9.x version emits a warning if you attempt to use a deprecated configuration file:

(node:38728) ESLintRCWarning: You are using an eslintrc configuration file, which is deprecated and support will be removed in v10.0.0. Please migrate to an eslint.config.js file. See https://eslint.org/docs/latest/use/configure/migration-guide for details. An eslintrc configuration file is used because you have the ESLINT_USE_FLAT_CONFIG environment variable set to false. If you want to use an eslint.config.js file, remove the environment variable. If you want to find the location of the eslintrc configuration file, use the --debug flag.
(Use node --trace-warnings ... to show where the warning was created)

Possibly this warning was hidden if ESLint was invoked by script.

Recommendation

• Short term workaround: use eslint-plugin-cypress@4.3.0.

• Refer to the ESLint migration guide and the README on how to use the current version of the plugin.

• See also the Releases section for details of what changed in each release.

I see. We were hoping to avoid running the eslintrc migration (https://nx.dev/docs/technologies/eslint/guides/flat-config) at this point in time because it seems to cause a lot of issues. So I will keep this package on 4.3.0 for a little while longer until we figure out what causes those problems.

Thanks for the explanation (I did miss the notice in the README, that's on me).

I'll close this issue.
