[Bug] ERR_MODULE_NOT_FOUND: exports declares ./lib/index.js but file is at ./lib/src/index.js (v5.5.0+)

[arunthiagarajan]

Environment

• expect-webdriverio version: 5.5.0+ (tested with 5.6.2)
• WebDriverIO version: 9.23.2
• Node.js version: 22
• OS: macOS / Linux (CodeBuild)

Description
Starting from version 5.5.0, expect-webdriverio has a packaging issue where the exports field in package.json points to a non-existent file.

** Expected behavior**
The exports field should point to the actual entry point file.

** Actual behavior**

Error [ERR_MODULE_NOT_FOUND]: Cannot find module '.../node_modules/expect-webdriverio/lib/index.js'
imported from .../node_modules/@wdio/runner/build/index.js

Root Cause
In package.json, the exports field declares:

"exports": {
  ".": [
    {
      "types": "./types/expect-webdriverio.d.ts",
      "import": "./lib/index.js"
    },
    "./lib/index.js"
  ]
}

But the actual file structure is:

lib/
├── src/
│   ├── index.js      ← Actual file location
│   ├── matchers.js
│   └── ...
└── tsconfig.build.tsbuildinfo

The entry point is at ./lib/src/index.js, not ./lib/index.js.

**Steps to Reproduce**
Create a new WebDriverIO project with ESM ("type": "module")
Install expect-webdriverio@5.6.2 and @wdio/local-runner@9.23.2
Run any WebDriverIO test
Error occurs immediately
**Workaround**
Pinning to version 5.3.4 works correctly:

**Suggested Fix**
Either:
Update exports to point to ./lib/src/index.js, or
Adjust the build configuration to output the entry point at ./lib/index.js
Affected Versions
✅ v5.3.4 - Works correctly (lib/index.js exists)
❌ v5.5.0+ - Broken (lib/index.js missing, file is at lib/src/index.js)
