error signing: code object is not signed at all

[chubin]

I am not sure that it is a big, and I rather suppose that I am doing something wrong, but maybe you could help me with this.

While signing a binary, I get the following error:

code object is not signed at all

I signed some other binaries, and it worked perfectly well, so I suppose the problem is with this binary only.
It is an electron app.
