error: Unhandled error: TypeError: Cannot read property ‘path’ of undefined

This issue get resolved when i delete by code and checkout again from svn.
This issue is very specific to iOS.
Here to start appium i am using AppiumDriverLocalService
Here i am setting path by HashMap env = new HashMap(); env.put(“ANDROID_HOME”, Constants.ANDROID_HOME); /** This to give the ANDROID_HOME path to AppiumDriverLocalService / env.put(“PATH”, “/usr/local/bin:” + System.getenv(“PATH”)); /* This to give the PATH to AppiumDriverLocalService for iOS testing */
After that service = AppiumDriverLocalService.buildService(new AppiumServiceBuilder() .usingDriverExecutable(new File("/Applications/Appium.app/Contents/Resources/node/bin/node")) .withAppiumJS(new File("/Applications/Appium.app/Contents/Resources/node_modules/appium/bin/appium.js")) .withIPAddress(Constants.APPIUM_SERVER_HOST) .usingAnyFreePort() .withStartUpTimeOut(60, TimeUnit.SECONDS) .withEnvironment(env) .withLogFile(new File(Constants.basePath + “/Logs/Appium.log”)))

Looks like you are quoting the boolean value. Boolean values don’t need to be quoted. Try this:

"autoAcceptAlerts":true

Tried. But still facing same issue.

Can you show the log where you tried? Also how you are setting that capability.

5

desiredCapabilities = new DesiredCapabilities();
Log.info(“Desired Capabilties object is created”);
desiredCapabilities.setCapability(MobileCapabilityType.DEVICE_NAME, Constants.deviceName);
desiredCapabilities.setCapability(MobileCapabilityType.PLATFORM_VERSION, Constants.devicePlatformVersion);
desiredCapabilities.setCapability(MobileCapabilityType.UDID, Constants.udid);
desiredCapabilities.setCapability(MobileCapabilityType.APP, app.getAbsolutePath());

            switch (Constants.devicePlatform.toLowerCase()){
            case "android" :
                desiredCapabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, MobilePlatform.ANDROID);  
                desiredCapabilities.setCapability(AndroidMobileCapabilityType.UNEXPECTED_ALERT_BEHAVIOUR, Constants.UNEXPECTED_ALERT_BEHAVIOUR);
                desiredCapabilities.setCapability(AndroidMobileCapabilityType.PAGE_LOADING_STRATEGY, Constants.PAGE_LOAD_STRATEGY);
                Log.info("Desired capabilties for Android is set");
                break;

            case "ios" :
                desiredCapabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, MobilePlatform.IOS);
                desiredCapabilities.setCapability(IOSMobileCapabilityType.AUTO_ACCEPT_ALERTS, true);

This comment has me thinking. Are you using any kind of IDE that might change the property to a String? It sounds like you wrote everything correctly and when you run it the first couple of times everything is fine, then something changes and you get the error. Deleting the code and checking out again solves the issue.

So the next time this happens, before you delete the code could you do an svn diff against master (or whatever the parent branch is)? Then you can see what’s changed and maybe get an idea of where this change is coming from.
