mdns is working correctly, however, when I try to build my image with "LICENSE_CREATE_PACKAGE = "1"" in my local.conf as described here https://www.yoctoproject.org/docs/2.8/dev-manual/dev-manual.html#providing-license-text I get this error message:

ERROR: mydevice-image-1.0-r0 do_rootfs: Postinstall scriptlets of ['mdns'] have failed. If the intention is to defer them to first boot,
then please place them into pkg_postinst_ontarget_${PN} ().
Deferring to first boot via 'exit 1' is no longer supported.

Do you have a solution? Why is it happening?
