0x1425ea42: FailedInnerCall

error FailedInnerCall()

What it means

A transaction that reverts with the raw data 0x1425ea42 hit the custom error FailedInnerCall, defined in OpenZeppelin 5. The explorer shows the hex because it does not have the contract's ABI to translate it.

A low-level call the contract made to another contract failed without a reason. The real failure happened one layer deeper.

How to fix it

A transaction decoder that traces internal calls can find the inner failure. From the outside, check the obvious causes first: approvals, balances, paused contracts.
