error details from the contract are not available for used of this library #2753

It seems that errors in the underlying contract do not always propagate with the sepcific error code.

For example, when using swapExactTokensForTokens and using tx.wait, the contract can return the error code INSUFFICIENT_OUTPUT_AMOUNT, but through ethers library, I get the generic CALL_EXCEPTION which indicates nothing about the actual error.

I would expect the original error from the underlying contract to be exposed in the exception details.
Alternatively, the important information that helps diagnose the problem should be present in the exception details

Is that a custom error? Are you including the custom error in the ABI?

it's in the solidity code - https://etherscan.io/address/0x7a250d5630b4cf539739df2c5dacb4c659f2488d#code (line #451)

That’s a normal Error(string) error. There should be a property on the error that contains that string. If not, can you include the entire error returned and what backend (default provider, infura, alchemy, etc) you are using?

The error string is only available when estimating gas. If the transaction was already sent (due to estimation was successful or gasLimit hardcoded), and tx failed later, the receipt does not contain any revert data hence it cannot be included in the error thrown.

If you want to view the revert data, the transaction needs to be executed again. If you have access to an archive node you would be able to do that.

const tx = await matic.getTransaction('0x192293c983c8ba7f7eb3b0b162d466354c2bc31db3120c69f0c22cdddc0008b2');
delete tx.gasPrice;
const result = await matic.call(tx, tx.blockNumber);
const iface = new Interface(['function Error(string)'])
ifacee.decodeFunctionData(result.slice(0,10), result);
