How do I read OpenBlocks tank amount?

Minecraft Version: 1.12.2
ComputerCraft Version: 1.89.2

I am trying to use ComputerCraft to read tank data from OpenBlocks tanks and output the fluid amount onto a monitor. Although it's not working and I am running into the issue where my code is not outputting an amount and just outputs 0. What am I doing wrong?
I would also like to figure out how to automatically read the tanks metadata to pull the fluid type automatically instead of me creating a fixed variable. Thanks!

Here is my setup:

Here is my code:
fluidtype = "Gaseous Fuel"
temperature = "21" -- This is going to be used for something else later on, it's currently just a placeholder.

tanks = {}
for i,v in ipairs(peripheral.getNames()) do
    if peripheral.getMethods(v).tanks then
        table.insert(tanks, peripheral.wrap(v))
    end
end

monitor = peripheral.find("monitor")
while true do
    sleep(.1)
    fluidamount = 0
    for _,tank in ipairs(tanks) do
        local fluids = tank.tanks()
        if fluids then
            for _,fluid in ipairs(fluids) do
                fluidamount = fluidamount + fluid.amount
            end
        end
    end
    monitor.clear()
    monitor.setCursorPos(1, 1)
    monitor.write("Type: "..fluidtype)
 monitor.setCursorPos(1, 3)
 monitor.write("Fill: "..fluidamount.."mB")
 monitor.setCursorPos(1, 5)
 monitor.write("Temp: "..temperature.."°C")
end

Try putting some print statements in your code and checking if the program is flowing as you expect it (e.g. if statements give true and their body runs).

I have the feeling that fluids might be a table that has string keys and thus needs pairs instead of pairs for the for loop.

I forget how stuff worked back in 1.12 so my advice is going to be limited.
