You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: async_assertion.go
    path of file: ./repos/kubernetes/vendor/github.com/onsi/gomega/internal
    
    the code of the file until where you have to start completion: package internal

import (
	"context"
	"errors"
	"fmt"
	"reflect"
	"runtime"
	"sync"
	"time"

	"github.com/onsi/gomega/forma
    
func (a asyncGomegaHaltExecutionError) Error() string {
	return `An assertion has failed in a goroutine.  You should call 

    defer GinkgoRecover()

at the top of the goroutine that caused this panic.  This will allow Ginkgo and Gomega to correctly capture and manage this panic.`
}
