Describe the bug

After the recent upgrade, the support for Solidity custom error is broken. Previously, it could return the function selector of the custom error that caused the transaction to be reverted when estimating gas/submitting the transaction.

Currently, if the transaction was reverted with a string reason, the error is like

"Failed to submit transaction: cannot estimate gas : [THE STRING ERROR REASON]."

However, for custom errors, the reason is no longer provided.

"Failed to submit transaction: cannot estimate gas."

Steps to reproduce

Call a transaction that will be reverted with Solidity custom errors.
