codesign: invalid argument "rce"

Hello,

I have codesigned quite a lot of apps in the past, but didn't do it for a while.

I codesign via the termial (no Xcode): codesign -s "MyCertificateName" --deep -force myApp.app

Now I get the error: invalid argument "rce"

I don't see, where I used an argument "rce" and what could be the issue here.

Any ideas what is going wrong here?

Thanks

Tiemo
