I think there is an issue with the PDF document, because it’s an issue
only with that PDF file I have. I can read the info from other files
pretty well.
I’m going to ask the author whether I may share the PDF document here,
so you can check it.

Sorry, I found in some document (or I found out it worked):
directives.enable(directives.enable("backend.date", "no")
But I never thought that an equal sign could be the way.
Many thanks for your help,
Pablo

Many thanks for your reply, Hans.
I’m afraid I don’t know how to extract the real information, I only get:
table: 0x324279a3400
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
BTW, how can I use "\enabledirectives[backend.date=2021.02.01]" in Lua?
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
