E2030 error

API not available in every flavor (shared flavor mode), missing a flavor guard

area: types (x2xxx)
fails the build: yes
in plain Lua files: reported as W2030

Shared flavor mode only ("build": { "flavor-mode": "shared" }): one build runs on several flavors, and this API doesn't exist on all of them. On a flavor without it, the name is nil in game, and using it raises an error. Guard the use with a flavor check (if flavor == "standard" then, a WOW_PROJECT_ID comparison) or an existence check (if C_Garrison then).

In a plain Lua file it is the warning W2030.

--!strictif C_Garrison then    C_Garrison.GetGarrisonInfo(1)end

The compiler reports it like this:

error[E2030]: `C_Garrison.GetGarrisonInfo` is not available in `vanilla`; guard it with a flavor check or an existence check
