It seems that there are errors thrown when signing Android 11 builds for release. This question was asked here (same error): https://community.nxp.com/t5/i-MX-Processors/Sign-Android-images-with-new-generated-keys/td-p/108893... , but a solution was not provided. The error is thrown in the sign_target_files_apks script:
sign_target_files_apks -o --default_key_mappings ./test_keys out/dist/*-target_files-*.zip signed-target_files.zip
