Seem to be getting this error as well.

There might be some error during the contract call. FWIK, some DEXes are suspended because of security issues. You might need to figure out that. Write a UT using hardhat's mainnet fork is a good way to debug because it can print the stack trace of error calls.

Sorry, I'm not maintaining this repo anymore. Actually, this is just for learning purposes.

@paco0x All good! I'll take a look and of course update this issue if I find anything out.
