fetchRemote does not support formFields arrays

[CrosRoad95]

Describe the bug

local sendOptions = {
    method = "POST",
    formFields = {
        a = {1,2,3}, // empty
        b = "123", // ok
        c = 123, // ok
        d = {{1,2,3},{3,2,1}} // empty
    },
}

fetchRemote( "https://webhook.site/3ac86286-0483-411c-b979-494da96ba55e", sendOptions, function()end )

a, and d are always empty

To reproduce
as above

Expected behaviour
only d should be empty

Bumping for visibility, this is still an issue.

@CrosRoad95 Did you ever find an alternative solution for this?
