# Daemon ADA Testing Tools - Critical Bug Fix

**Date:** 2025-10-02  
**Issue:** All new ADA accessibility testing tools failing with JSON parsing error  
**Status:** ✅ FIXED

## Problem Description

All newly implemented ADA testing tools were failing with the error:
```
failed to parse results: invalid character 'm' looking for beginning of value
```

### Root Cause

The functions were using `jsResult.Value.String()` which returns Go's string representation of objects (like `"map[key:value]"`) instead of JSON. The correct approach is to either:
1. Use `jsResult.Value.Str()` for string values
2. Use `jsResult.Value.Map()` for object values
3. Have JavaScript return `JSON.stringify(result)` and then use `.Value.Str()`

## Functions Fixed

### 1. `checkContrast` (daemon/daemon.go:8889)
**Change:** Modified JavaScript to return `JSON.stringify(results)` instead of `results`
**Change:** Modified parsing from `.Value.String()` to `.Value.Str()`

```go
// Before:
return results;
resultsJSON := jsResult.Value.String()

// After:
return JSON.stringify(results);
resultsJSON := jsResult.Value.Str()
```

### 2. `testKeyboardNavigation` (daemon/daemon.go:9170)
**Change:** Modified JavaScript to return `JSON.stringify(results)` instead of `results`
**Change:** Modified parsing from `.Value.String()` to `.Value.Str()`

```go
// Before:
return results;
resultsJSON := jsResult.Value.String()

// After:
return JSON.stringify(results);
resultsJSON := jsResult.Value.Str()
```

### 3. `testZoom` (daemon/daemon.go:9373)
**Change:** Modified JavaScript to return `JSON.stringify(result)` instead of object
**Change:** Modified parsing from `.Value.String()` to `.Value.Str()`

```go
// Before:
return {
    viewport_width: window.innerWidth,
    ...
};
err = json.Unmarshal([]byte(jsResult.Value.String()), &zoomTest)

// After:
return JSON.stringify({
    viewport_width: window.innerWidth,
    ...
});
err = json.Unmarshal([]byte(jsResult.Value.Str()), &zoomTest)
```

### 4. `testReflow` (daemon/daemon.go:9622)
**Change:** Modified JavaScript to return `JSON.stringify(...)` instead of object
**Change:** Modified parsing from `.Value.String()` to `.Value.Str()`

```go
// Before:
return {
    width: window.innerWidth,
    ...
};
err = json.Unmarshal([]byte(jsResult.Value.String()), &breakpoint)

// After:
return JSON.stringify({
    width: window.innerWidth,
    ...
});
err = json.Unmarshal([]byte(jsResult.Value.Str()), &breakpoint)
```

### 5. `runAxeCore` (daemon/daemon.go:8673)
**Change:** Modified to use async/await for Promise handling and stringify results
**Change:** Modified parsing from `.Value.String()` to `.Value.Str()`

```go
// Before:
runCode := fmt.Sprintf(`() => {
    return axe.run(%s);
}`, optionsJSON)
resultsJSON := jsResult.Value.String()

// After:
runCode := fmt.Sprintf(`async () => {
    const results = await axe.run(%s);
    return JSON.stringify(results);
}`, optionsJSON)
resultsJSON := jsResult.Value.Str()
```

**Note:** axe.run() returns a Promise, so we needed to add `async/await` handling.

## Testing Required

After rebuilding and redeploying the daemon, test each function:

1. **Contrast Check:**
   ```bash
   # Should return detailed contrast analysis without errors
   cremote contrast-check --selector body
   ```

2. **Keyboard Navigation Test:**
   ```bash
   # Should return tab order and focus indicator analysis
   cremote keyboard-test
   ```

3. **Zoom Test:**
   ```bash
   # Should test at 100%, 200%, 400% zoom levels
   cremote zoom-test --zoom-levels 1.0,2.0,4.0
   ```

4. **Reflow Test:**
   ```bash
   # Should test at 320px and 1280px widths
   cremote reflow-test --widths 320,1280
   ```

5. **Axe-Core Test:**
   ```bash
   # Should inject and run axe-core tests
   cremote inject-axe
   cremote run-axe --run-only wcag2a,wcag2aa,wcag21aa
   ```

## Deployment Steps

1. **Rebuild the daemon:**
   ```bash
   cd /home/squash/go/src/git.teamworkapps.com/shortcut/cremote
   go build -o cremotemcp ./daemon
   ```

2. **Rebuild the MCP server:**
   ```bash
   cd mcp
   go build -o cremote-mcp
   ```

3. **Restart the cremote daemon container** (deployment-specific)

4. **Verify fixes** by running the test commands above

## Files Modified

- `daemon/daemon.go` - 5 functions fixed (lines 8673-8715, 8889-8931, 9170-9210, 9373-9431, 9622-9688)

## Impact

- ✅ Fixes all ADA testing tool failures
