then you're doing something wrong
\startluacode
local main = lpdf.epdf.load("ar.pdf")
context(tostring(main.Info.ModDate))
context(tostring(main.Info.Title))
local crap1 = tostring(main.Info.ModDate)
local crap2 = tostring(main.Info.Title)
context(crap1)
context(crap2)
\stopluacode
works quite okay

grep is your friend ... (probably also in the cld manual)
directives.enable('backend.date=2021.02.01')
which of course doesn't mean that each one will work out as expected
because timing matters
