Sounds like you are not on the latest package version. Please specify the exact package version you are on (3.1 has 37 releases)

@patrickbrouwers I got the same issue.

Laravel version: 9.9.0

Laravel Excel version: 3.1.38

Error:

I add the attribute to file \Maatwebsite\Excel\Validators\Failure::jsonSerialize() as it says and that error disappears.
