• Place a ma after rules { } – Krausladen Commented Mar 16, 2022 at 14:05
• @Krausladen this would make the JSON invalid. – JSON Derulo Commented Mar 16, 2022 at 14:10
• You're getting an ESLint error reported. Probably the code builds and works just fine. Seems like you have not configured ESLint properly to work with TypeScript. – JSON Derulo Commented Mar 16, 2022 at 14:11
• You might want to add and configure typescript-eslint in your project. – JSON Derulo Commented Mar 16, 2022 at 14:12

In the current configuration, eslint cannot deal with TypeScript. The following steps enable TypeScript support.

• Run npm install --save-dev @vue/eslint-config-typescript
• Adapt the ESLint config:
  • Remove "parser": "@babel/eslint-parser" from the parserOptions
  • Add "@vue/typescript/remended" to the extends key

Based on your file above, it would look like this:

{
  "root": true,
  "env": {
    "node": true
  },
  "extends": [
    "plugin:vue/essential",
    "eslint:remended",
    "@vue/typescript/remended"
  ],
  "parserOptions": {},
  "rules": {}
}

Depending on your ESLint version, the installation of @vue/eslint-config-typescript might result in a dependency conflict. With ESLint < 9 you'll have to install @vue/eslint-config-typescript@10

If Code Works Then You need to configure esLint if it throw an error then u need to place correctlly place it between {}

My issue was caused by find. Vue error message is not help full

 <p v-if="clients" class="text-sm text-gray-400">
     No open or available details for 
    {{ clients.find((c: IClient) => c.id === selectedValue)[0]}}
 </p>

I made a mistake find will return IClient object not an array

Solution: Double check your code

 <p v-if="clients" class="text-sm text-gray-400">
         No open or available details for 
        {{ clients.find((c: IClient) => c.id === selectedValue)?.pany }}
     </p>
