# 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
- ✅ Enables comprehensive WCAG 2.1 AA compliance testing
- ✅ No breaking changes to API or command-line interface
- ✅ No changes required to client code or MCP tools
