TOML.parsefile error on reading date formatted variable

I have the test.toml file, containing the single line:

period = 2021-04-20 # should be formatted as YYYY-MM-DD

When I try to parse it via:

julia> using TOML
julia> TOML.parsefile("test.toml")

the following error arises:

ERROR: TOML Parser error:
/home/orca/Dropbox/work/study/computing/Julia/sandbox/test.toml:1:21 error: expected newline after key value pair
  period = 2021-04-20 # should be of type Date 
 [1] parse
   @ ./toml_parser.jl:441 [inlined]
 [2] parsefile(f::String)
   @ TOML /buildworker/worker/package_linux64/build/usr/share/julia/stdlib/v1.6/TOML/src/TOML.jl:43
 [3] top-level scope
   @ REPL[2]:1

If I delete the comment: # should be formatted as YYYY-MM-DD in the original test.toml file, it is correctly parsed:

julia> TOML.parsefile("test.toml")
Dict{String, Any} with 1 entry:
  "period" => Date("2021-04-20")

How can I use an end of line comment in the .toml file for a field formatted like period? In principle, I would like to keep the comment, in the same line, to help the user input correctly the value for the variable period. Of course, there are two ways around this, which I’d rather not use:
(1) move the comment to a line by itself, right before the line declaring period,
(2) not using any comment at all.
