I used the

attempt()

of IO. Like this:

someCommand(IO.monadDefer(), arg1)
                    .fix()
                    .attempt()
                    .unsafeRunSync()
                    .fold({ error ->
                        raiseError<List<Log>>(createErrorLogs("It was not possible to run the command", error))
                    }, {
                        just(it)
                    })
                    .bind()
