Problem Description

Here's the gist: https://gist.github.com/n2nco/eabb6765ffbe895cfa8e2449fce40e2d
Need to fix this file! Getting error "execution reverted" when running this!

This file (gist) attempts to use instadapp's dsa-connect to do a uniswap swap.
Then it attempts to simulate that transaction using alchemy (currently commented out).

Acceptance Criteria

Fix this gist's express route to:

1. perform a DefiSmartAccount (DSA) uniswap swap based on the inputs in the req
2. & also have this simulate the transaction using the alchemy api call

This route should return:

1. uniswap broadcasted spell tx hash 2) the unsigned transaction 3) the alchemy tx preview response

Ideally this should work on whichever chainid (e.g. 1 = mainnet, 137 = polygon, 5 = goerli testnet) is passed in. Input token address e.g. UNI, and output token address (e.g. USDC) should also be passed in through the req.

If you post a repl or gist that works I'll accept the 1st answer I see!

Any questions or clarifications email me at askprogrammers@gmail.com - if your code works well (e.g. dynamic based on args passed in) I'm open to contracting more interesting work to you!

Technical Details

Typescript or JS works for me - whichever you prefer.
You'll need an alchemy api key (free & easy to obtain), and some type of crypto account to test this file out.
