Make Fields required dynamically in code

Hello,

Here is an example of how to change the Required

viewModelConfig: /**SCHEMA_VIEW_MODEL_CONFIG*/{
            "attributes": {
                "UsrCustomText": {
                    "validators": {
                        "required": {
                            "type": "crt.Required"
                        }
                    }
                },
....
 
{
                request: "crt.HandleViewModelAttributeChangeRequest",
                handler: async (request, next) => {
                    if (request.attributeName === 'LookupAttribute_nj0qj8x') {
                        const accountAddressModel = await sdk.Model.create("AccountAddress");
                        const filters = new sdk.FilterGroup();
                        await filters.addSchemaColumnFilterWithParameter(sdk.ComparisonType.Equal, "Account", request.$context.Id.__zone_symbol__value);
                        
                        const address = await accountAddressModel.load({
                            attributes: ["Id"],
                            parameters: [{
                                type: sdk.ModelParameterType.Filter,
                                value: filters
                            }]
                        });
                        if (address.length > 0) {
                            request.$context.enableAttributeValidator('UsrCustomText', 'required');
                        } else {
                            request.$context.disableAttributeValidator('UsrCustomText', 'required');
                        }
                    }
                    return next?.handle(request);
                }
            }

However, this code is currently not working, the fix to it will be added in a version 8.0.10
