Empty line when using «send mail message» action

Good evening everyone.

I have KM ver. 10.2 and Ventura 13.4

Every time I use the send mail message action, an empty line is left at the beginning of the message, whereas there is none.

It happens all over my macros.

Any hint?

Thank you and have nice evening.

That looks to be Apple’s fault I'm afraid. I get the same result with this simple AppleScript:

tell application "Mail"
	set theNewMessage to make new outgoing message with properties {subject:"Hello", content:"There", visible:true}
end tell

Thank you
