How to make a simple swap on devnet?

On devnet

I need to make a simple swap operation and as one time operation, as a test.

I need it in the form of 3 types: SOL -> token, token -> SOL, token -> token

Initially I have 10 SOL on my dev account. I've tried to eliminate all the stuff from that I may not need from jupiterSpotSwap(....) and then call this function in the end of init(...). I specified subAccountIndex = 0 and marketIndex = 0 too.

It's not worked. But there'll be some or other error at runtime still, for instance:

error: Error trying to long spot position for market 0 on jupiter, subaccount start 0

How will I make a simple swap then? Is there any simple example?

And what preliminary work have I make for this: open a position, set up something.... ? And how?
