Hello - I am building an app that calls the [https://civicinfo.googleapis.com/civicinfo/v2/representatives](https://civicinfo.googleapis.com/civicinfo/v2/representatives) api. Depending on what the user enters in the input field, when it is used as a parameter to the api, sometimes the resulting JSON will not contain all the properties. Then when I call ‘get property of object’ with the expected property name, the app crashes. How do I capture the exception or query on the property without the application crashing? ---

@mpokrzywinskimc6ua There is no easy way to know if the property exists or not. The workaround presented by @jaythemanchs and @Balanced_Kitchen actually works but will make your code too long and too involved. The best workaround I found is to use ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/1/c/1c7271cc7836e8cb96825ff833c373bb52d37463.png) which will give you a list of all properties in the object. You can then easily check the availability by using the blocks in the list drawer ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/6/d677e476afd242c7666337b6311fc331b3566635.png) which you can verify all required properties before displaying the contents. With this method you can have a function that does the checking of all required properties and then you display the values of those available properties only. ---

Thank you! This did work, @jaythemanchs, to catch the error when the properties are not part of the returned JSON. ![Working Error Checking](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/f/f/ff927c3edf24f16043767b31051d528f11e57561.jpeg) ---
