Notarization problem (with DMGCanvas) : Hardened runtime not enabled

Hello,
I use DMG Canvas 4 to sign and notarize my application.
The DMG image is well generated and signed but I have the following error which prevents the notarization of the application:
“The executable does not have the hardened runtime enabled.”
What can I do ?
Thanks.

Status: Invalid
Archive contains critical validation errors
• [ERROR] <MicMac> The executable does not have the hardened runtime enabled.

Talk to Araelium. If they’re offering signing & notarization, they need to be adding the “hardened” option as well.
