Please help
I am new to this and need some help please. I am installing an app on a site but have got a load of errors. Is it ok if I post a link? Thanks
Level 11
SHow what you have in your middleware where the error is coming from and also the code that trigeers the error itself
Level 1
Thank you but I'm not allowed to post code
Level 104
You can post your code; simply wrap your copy/pasted code snippet inside triple backticks, e.g.
```
// your code
```
You need to ensure that the Middleware returns a Response, or eventually delegate to the next Middleware in the stack:
return $next($request);

Just as @tykus has stated you have the followng missing

you can install vscode and intelliphense or devsense plugins for free, and kill all these errors as you type them!
