Problem/Motivation
Steps to reproduce
1) Create a new webform or use existed.
2) Add a new fields with "integer" type.
3) Add a new field with "computed twig" type and define some math in this field (e.g. integer_field1 + integer_field2).
4) Up to version 6.1.4 (version 6.1.3. and below) computed twig has worked correctly with any math operations for integer type fields at least.
5) After upgrade to 6.1.4 a see the errors:
TypeError: Unsupported operand types: string + string в __TwigTemplate_bfbe80d8718ade6a257b26a4b227924a->doDisplay() (строка 39 из /var/www/html/***/web/sites/default/files/php/twig/641018ae23296___string_template__a5e22e_Rn-FNXHTsTJtUZJ-SBX7BYDy6/OBR8lut5eq4XgaocKlwHwG6ag6RUqxkUkrl7oIB3_1M.php)
Here the line 39 from generated twig template:
echo $this->extensions['Drupal\Core\Template\TwigExtension']->escapeFilter($this->env, ((twig_get_attribute($this->env, $this->source, ($context["data"] ?? null), "integer_field_1", [], "any", false, false, true, 1) + twig_get_attribute($this->env, $this->source, ($context["data"] ?? null), "integer_field_2", [], "any", false, false, true, 1)) / 2), "html", null, true);
In my example, I'm trying to add two fields and divide the sum by 2 (this worked fine until the module was upgraded to version 6.1.4)
6) When I try to follow the webform result page or any submission with computed twig fields site just show me the error "The website encountered an unexpected error. Please try again later."
