Hi guys! I’m trying to make a middleware with InputFilter in mezzio however I have had the following error:

“Unable to resolve service “App\InputFilter\UserInputFilter” to a factory; are you certain you provided it during configuration?”

It only fails in the middleware if I use InputFilter in the handler it works correctly, I’m based on the configuration indicated by the site.

https://docs.laminas.dev/laminas-inputfilter/application-integration/usage-in-a-mezzio-application/

Has anyone had the same problem?

Input filters must be retrieved from the InputFilterPluginManager, so inside your Middleware/Handler factory, you’d first make a call to $inputFilterManager = $container->get(InputFilterPluginManager::class); and your filter would be available to pass to your Middleware constructor like return new MyMiddleware($inputFilterManager->get(MyInputFilter::class)); - I hope that’s helpful.

The required code example for the factory is included in the documentation which you have linked:
