So if I've got this right, you've wrapped a Ticket Machine as a peripheral, and attempting something like this:

local booleanInfo = TM.createTicket("South/SeaStation")

… triggers the error, but the machine still creates the ticket. It acts this way whether you run the line via your script, or directly via the Lua prompt.

Is that all correct?

yes thats correct

I tried the line with a Ticket Machine myself under a couple of different mod packs, and couldn't get that behaviour.

Seemed to work perfectly under Unleashed 1.1.3, while under DW20 1.0.11 the game initially crashed before I could try. My second attempt revealed that version can't access the ticket printing functions at all.

There are other recentish reports of stability issues with the Ticket Machine, so were I you I'd be checking my current versions and considering updating. Assuming that doesn't help, you may, with luck, get somewhere with the pcall (protected call) function.

I've not tried it, but I believe it'd go something like this:

pcall(TM.createTicket,"South/SeaStation")

Well atm i'm on a Direwolf20 1.6.4 server and we are runing 1.0.1.4 verson. We did have some issues with the ticket machine in 1.0.1.2 but that was due to a bug causeing the computer not to reckognice the ticket machine as a peripheral.
Well hx for te help
