Resigning ableton for debugging

Anyone know why this would fail (from @McMartin 's script);

+ codesign --force --options runtime --sign - --entitlements /tmp/debug_entitlements.plist '/Applications/Ableton Live 10 Suite.app/Contents/MacOS/Live'
/Applications/Ableton Live 10 Suite.app/Contents/MacOS/Live: replacing existing signature
/Applications/Ableton Live 10 Suite.app/Contents/MacOS/Live: code object is not signed at all
