Hide Azure Function response error

I run an Azure Function from my PowerApp (a http trigger POST) and even when it works without a problem and it just returns '200', I get the following error in my PowerApp:AzureFunctionError.png

"AzureFunction.FunctionName failed: the data returned in the response is invalid."

How do I get this to not show up? The function works fine and I don't need it to return anything.

Or is this something I should ask on a Azure Function forum?

Pretty new to working with Azure.

Maybe you havent specified a default response for the custom connector action?

There shouldn't be a problem with the response.

I have a different custom connecter which I call through flow instead of directly, with the same response and that never gives an error. Maybe I'll just add this one through flow as well instead of directly, but it'd be nice to know what I did wrong anyway.

This is what I do:

Function: Return something: Out-File -Encoding utf8 -FilePath $res -inputObject (ConvertTo-json @{"status"="$Message"})

Connector: Set a default response by sample: {"status": "Hello"}

App: Call the endpoint and store the result: Set(sStatus,MyCon.CreateList(Title:TextTitle.Text).status)
