}

@lacksinho and the error comes from validation?

Can I suggest that you add the file rule

'excel_file' => ['required', 'file', 'max:1024', new FileExtensionRule($this->arrayExtension)] 

@Sinnbeck

Again still the same error

@lacksinho check the stack trace in the error to see where in your code the error originates. Or share the error page

@lacksinho did you find a solution? I have the same problem
