These are the expressions I have tried (unsuccessfully):\r\n\r\n```\r\n$[\"cd[DataLayer]\"]\r\n$['cd[DataLayer]']\r\n$.cd[DataLayer]\r\n$.cd`[DataLayer]\r\n$.cd`[DataLayer`]\r\n$['`cd[DataLayer]']\r\n$['cd`[DataLayer]']\r\n$['cd`[DataLayer]`']\r\n$[?(@.property == 'cd[DataLayer]')]\r\n$.cd\\[DataLayer\\]\r\n$.cd.DataLayer\r\n$[`cd[DataLayer]]\r\n$[cd[DataLayer]]\r\n```\r\n\r\n### Console error or logs\r\n\r\nNo errors for any of the expressions listed above, but they all return an empty result (`[]`).\r\n\r\n## Expected behavior\r\n\r\nI would expect there to be some expression that can select the `cd[DataLayer]` property.\r\n\r\nAs per the json-path-comparison project, `$[']']` should return `[42]` for the input `{\"]\": 42}`, which fails in jsonpath-plus: https://cburgmer.github.io/json-path-comparison/results/bracket_notation_with_quoted_closing_bracket_literal.html#JavaScript_jsonpath-plus\r\n\r\n## Expected result\r\n\r\n```json\r\n[\r\n  1\r\n]\r\n```\r\n\r\n## Environment (IMPORTANT)\r\n\r\n- Locally using JSONPath-Plus version: 7.2.0\r\n- And on the [demo page](https://jsonpath-plus.github.io/JSONPath/demo/?)\r\n\r\n## Desktop\r\n\r\n - Firefox 132.0b5 on Ubuntu 24.04.1 LTS\r\n - Node v20.7.0\r\n\r\n","author":{"url":"https://github.com/baltpeter","@type":"Person","name":"baltpeter"},"datePublished":"2024-10-14T14:11:50.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/225/JSONPath/issues/225"}
