Answer 1

I don't know how to correct fix it, but I just reverted

symfony/twig-bridge to v4.2.8
twig/twig to v2.10.0

And all ok for me now. I hope it help you.

I set in composer.json

"symfony/twig-bridge": "4.2.8",
"twig/twig": "2.10"

and updated composer.

This error was caused by an issue at @SonataAdmin/CRUD/base_edit_form.html.twig . It is fixed at v3.49.0 . See the related PR .
