The feedback has been submitted with bug number FB15488021

I had the very similar issue on our build machine with TeamCity installed. The build and notary script even works smoothly when it is being called manually on the build machine. But when the building process is triggered automatically, such as a nightly build, it failes with: Info [KEYCHAIN] No Keychain password item found for: AC_PASSWORD The solution for me was that the keychain profile has to be stored in the login keychain, but not in the default iCloud/Login Items keychain when running the comand "notarytool store-credentials", otherwise the keychain profile, no matter app-specific-password or App Store Connect Key won't be listed by 'security find-generic-password -l '. I think there must be a bug related to "notarytool store-credentials" and "security find-generic-password -l".
