I made an api and something went wrong.
Here is my code:
rednet.open("right")
function server( sPath )
while true do
local event, nId, message = os.pullEvent()
if event == "rednet_message" then
fs = io.open(sPath..message..".txt", "r")
page = fs:read("*a")
fs:close()
rednet.send(nId, page)
end
end
end
function client( SCID, sPage )
rednet.send(SCId, sPage)
id, message = rednet.receive(5)
return message
end
Here is the error:
internet:1: attempt to index ? (a nil value)
I don't know where the error is.

Is there more to the code? You probably just need to define sPath prior to the function.

Not necessarily, the line it reports is not always the offending line.
The rednet.open("right") is correct as long as there is a bundled cable or modem attached to that side of the computer.
Hmmmm I realized this is an API… Try moving the rednet.open() into the function, or just remove it from the API and add it to the program.

Somehow you can't really use other APIs (often) in an custom API. For example shell.run("clear") isn't working either
