Notarization Successful but Stapling Fails with Error 65

Product: macOS, Notarization Tool: notarytool, Stapler Tool: xcrun stapler, Application: master-billing.app, DMG: master-billing.dmg

I'm attempting to notarize and staple a macOS .dmg file containing a signed .app. Notarization completes successfully, but the stapling step fails with Error 65. All tools are up-to-date and I'm following the official Apple process.

#!/bin/bash set -e

APP="dist/mac-arm64/master-billing.app" DMG="dist/mac-arm64/master-billing.dmg" IDENTITY="Developer ID Application: NAME (TEAM ID)" PROFILE="notarysiva" VOLUME_NAME="MasterBilling"

Sign binaries and frameworks

find "$APP" -type f ( -name ".dylib" -or -name ".so" -or -name "*.node" -or -perm -u+x )
-exec codesign --force --options runtime --timestamp --sign "$IDENTITY" {} ;

find "$APP" -type d ( -name ".app" -or -name ".framework" )
-exec codesign --force --options runtime --timestamp --sign "$IDENTITY" {} ;

codesign --deep --force --options runtime --timestamp
--sign "$IDENTITY" "$APP"

Create DMG

hdiutil create -volname "$VOLUME_NAME" -srcfolder "$APP" -ov -format UDZO "$DMG"

Sign DMG

codesign --sign "$IDENTITY" --timestamp "$DMG"

Verify DMG signature

codesign --verify --verbose=2 "$DMG"

Submit for notarization

xcrun notarytool submit "$DMG" --keychain-profile "$PROFILE" --wait

Staple ticket

xcrun stapler staple -v "$DMG"
