Which branch to use to build A15 based /e/ for the ASUS Zenfone8

Historically I was caught out by change of use of branch vs tags as mentioned by @piero in the thread he linked – I wonder if that changed again and / or the community script has not been updated (??) as illustrated by @jigsaw.

At first sight this part of the error

DEVICE_LIST_V3.0.4-A15: invalid variable name

does not appear to derive from your input.
