@kokokenada in your function configuration, you specify the name of $return for the output. By using the keyword $return, you are telling the azure function to just accept whatever value is returned from the function. The default, res, requires you to set the res value on the context object for the result. Check out the docs for more info. This is only the case for output bindings. It doesn't make sense to return for an incoming binding. Please reach out if you have other questions
