Installing Lineageos on Essential ph-1. Stuck on fastboot flash boot boot.img

I am trying to install latest Lineageos for mata on Essential ph-1. It is stuck at fastboot flash boot boot.img with the warning about avb, boot partition size of 0. Boot image size: 33673216 and fastboot getvar partition-size:boot returns partition-size:boot: 0201d000. The boot image is larger than the partition. The boot image (33673216 bytes) is larger than the reported boot partition size (33671168 bytes, which appears as '0' in the fastboot warning due to an error). How do I fix this and get lineage OS installed on Essential ph-1?
