Battery block doesn't show up when alone

[kleescian]

This works fine:

local blocks = {
    oxwm.bar.block.datetime({
        format = "{}",
        date_format = "%a, %b %d - %-I:%M %P",
        interval = 1,
        color = colors.cyan,
        underline = true,
    }),
    oxwm.bar.block.static({
        text = " │  ",
        interval = 999999999,
        color = colors.lavender,
        underline = false,
    }),
    -- Uncomment to add battery status (useful for laptops)
     oxwm.bar.block.battery({
         format = "{}%",
         charging = "⚡ {}%",
         discharging = "- {}%",
         full = "✓ {}%",
         interval = 30,
         color = colors.green,
         underline = false,
     }),
};

While this shows an empty bar:

local blocks = {
    oxwm.bar.block.static({
        text = " │  ",
        interval = 999999999,
        color = colors.lavender,
        underline = false,
    }),
    -- Uncomment to add battery status (useful for laptops)
     oxwm.bar.block.battery({
         format = "{}%",
         charging = "⚡ {}%",
         discharging = "- {}%",
         full = "✓ {}%",
         interval = 30,
         color = colors.green,
         underline = false,
     }),
};

It seems like having any non-static block before makes the battery block work.
