# Error: Context provider is missing a 'value' prop. The context will receive undefined.

- **ID:** `react/context-provider-missing-value`
- **Domain:** react
- **Category:** runtime_error
- **Verification:** ai_generated
- **Fix Rate:** 95%

## Root Cause

A React Context Provider component is rendered without a 'value' prop, causing consuming components to receive undefined instead of the intended context value.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|

| React 17.0.2 | active | — | — |

## Workarounds

1. **Ensure the Provider component always includes a 'value' prop, even if it's an empty object or a fallback.** (95% success)

## Dead Ends

- **Adding a default value to createContext() to avoid undefined** — The default value is only used when there is no Provider at all; if a Provider is present without value, the default is ignored and undefined is passed. (70% fail)
- **Wrapping the Provider in a conditional to skip rendering if no value is available** — This may hide the error but leads to missing context for consumers, causing runtime errors later. (60% fail)
- **Setting value to null explicitly, thinking it's the same as missing** — null is a valid value and will be passed; the error is specifically about the prop being absent, not its value. (50% fail)
