Swap Example: Multi hop swaps are not working

## How to reproduce:

Swap any token that needs more than 1 "route".

The transaction does go through but in the block explorer (and in the console) you can see the following error message.

> failed to execute message; message index: 0: function swapExactAmountIn failed due to internal reason: {ReadFlat}

This may be because something changed from the Osmosis side, related to the new pool types.
