Hi @pranavkirtani, could you provide a code snippet? I was able to push a transaction using v3 without error;
You are most likely passing in the incorrect contracts. Look here for the UiPoolDataProviderV3 and PoolAddressesProvider-[network] address's. Here is a repo I've been building that successfully uses this library to create borrow and supply positions (still working on other features) I'm adding more of the needed contract address but it works on mumbai.
I'm facing the same problem when executing the tx from borrow method, but i was able to run supply method.
Plus seems like the snippet in readme is wrong for borrow(v3)
Gas estimation error is a generic error for a failing transactions. Most common issues can be:
- Invalid asset address
- Insufficient balance
If you have a failed txHash we can debug the exact error.
