[@MyDaniel128]

hey, when I try to run the tests the response is still { "statusCode" : 200, "body" : "\"Hello from Lambda!\""} , it's like I run the default lambda function , like I didn't modify the function. Can you help me out please ?

Hi @Daniel Pop, are you still having problems?

[@MyDaniel128]

@@NKTStudios no, i have figured it out, i needed to press the deploy button for the function to update from the default one
