Maatwebsite\Excel\Validators\ValidationException:给定数据在Laravel中无效

在我的Laravel-5.8项目中，我使用Maatwebsites-3.1导入excel

进口

<?php
namespace App\Imports;
use Maatwebsite\Excel\Concerns\WithMultipleSheets;

class LeavesImport implements WithMultipleSheets
{
    public function sheets(): array
    {
        return [
            new FirstLeaveSheetImport()
        ];
    }
}

控制器

public function import(Request $request){
    $request->validate([
        'file' => 'required|max:10000|mimes:xlsx,xls',
    ]);

  $path1 = $request->file('file')->store('temp'); 
  $path=storage_path('app').'/'.$path1;  

    try{

        Excel::import(new LeavesImport, $path);      
        
    } catch (\Maatwebsite\Excel\Validators\ValidationException $e) {
        $failures = $e->failures();
        Log::error($e);
        $errormessage = "";            

     // dd($failures);
     foreach ($failures as $failure) {
         $errormess = "";
         foreach($failure->errors() as $error)
         {
             $errormess = $errormess.$error;
         }
         $errormessage = $errormessage." ,\n At Row ".$failure->row().", ".$errormess."<br>";
     }
         // Session::flash('error', 'Excel file is not imported!');
         Session::flash('error', $errormessage);
         // return redirect()->route('leave.leave_adjustments.index');  
         return back();            
    }catch (\Illuminate\Database\QueryException $e)
    {
        $errorCode = $e->errorInfo[1];
        if($errorCode == 1062){
        Log::error($e);
        DB::rollback();
        Session::flash('error', 'You have a duplicate entry problem!');
        }
        return back();

    }
    
    Session::flash('success', 'Leave Records Imported Successfully');
    return redirect()->route('leave.leave_reviews.index_hr');         
}

如何检测和纠正错误

感谢来自

试试看{
$import->import（'import-users.xlsx'）；
}捕获（\Maatwebsite\Excel\Validators\ValidationException$e）{
$failures=$e->failures（）；
foreach（$failures作为$failure）{
$failure->row（）；//出错的行
$failure->attribute（）；//标题键（如果使用标题行关注点）或列索引
$failure->errors（）；//来自Laravel验证程序的实际错误消息
$failure->values（）；//失败行的值。
}
}

}

如果有提示，请尝试查看

$e->errors（）

以及

$e->failiures（）

there@apokryfos-它没有显示任何错误。我通过Log：：error（$e）得到的所有信息；错误日志中显示的是我在上面的错误日志中显示的内容。如果有提示，请尝试查看
