When I use Object Spy, I have encounted an error " cannot connect to Katalon server. Make sure you have started Object Spy on Katalon application" after pressed “alt + ~”.
Sorry for the late response.
Please check if you’ve already opened ‘Object Spy’ dialog from Katalon Studio when you are going to capture elements Firefox as shown in this image below:
Otherwise, our Firefox’s extension can’t connect to Katalon Studio and will throw out that error message
Do I miss to set up anything?
Please start Object Spy from Katalon Studio and select the correct ‘instant browser’ with the browser you are spying on
