Unable to use "u" filter

Question

I am unable to get my symfony 4 application to run.

The error I get below indicates the filter is not found despite making sure twig/string-extra which includes "symfony/string": "^5.0"is in my composer file.

I have the activated twig extensions in twig_extensions.yml as follows:

services:
  _defaults:
    public: false
    autowire: true
    autoconfigure: true

    # Uncomment any lines below to activate that Twig extension
    #Twig\Extensions\ArrayExtension: ~
    #Twig\Extensions\DateExtension: ~
    Twig\Extensions\IntlExtension: ~
    #Twig\Extensions\TextExtension: ~

The specific line causing the issue looks like this: {{- label|u.truncate(100) -}}

The file in vendor/sonata-project/admin-bundle/src/Resources/views/standard_layout.html.twig line 175

Unknown "u" filter. Did you mean "round", "upper", "column", "reduce", "default", "truncate", "humanize", "yaml_dump", "url_encode", "number_format", "sonata_slugify", "sonata_truncate", "localizednumber", "sonata_urlsafeid", "localizedcurrency", "knp_menu_as_string", "sonata_status_class", "form_encode_currency", "doctrine_pretty_query", "doctrine_replace_query_parameters"?

Did you register the extra extension within twig? See [here](https://symfony.com/doc/current/templating/twig_extension.html#register-an-extension-as-a-service) — DarkBee, Jun 17 '20 at 05:42
@NicoHaase This is a filter that should already be in Twig so my thinking is that the registration should work with auto wiring? — Masinde Muliro, Jun 17 '20 at 07:10
This is not a default twig filter as seen [here](https://twig.symfony.com/doc/3.x/). Also the extension is called `StringExtension ` and is not present in your yaml — DarkBee, Jun 17 '20 at 07:18
Thank you, you're right. Apologies for my ignorance. Issue is fixed — Masinde Muliro, Jun 17 '20 at 07:38
