I have been developing A front-end project with Angular. Back-End side has been develeoped with netCore.

On back-end Side Validation Rules results returning with throw method Like this;

And I only need validation rules string in it to show them on the Page.

I Mean,I have no chance to change Back-End that's why have to filter it. Only need this

Name: Name can not be null Address: Addrees con not bu null Severity Address: Addres must be at least 3 charecter Severity

Is it possible to Fİlter it?

FluentValidation.ValidationException: Validation failed: -- Name: Name can not be null: Error -- Address: Addrees con not bu null Severity: Error -- Address: Addres must be at least 3 charecter Severity: Error at Core.Validations.FluentValidation.ValidationTool.Validate(Object entity, IValidator validator) in C:\Users\atakan.gunay\source\repos\EReconcilationBackendProject\Core\Validations\FluentValidation\ValidationTool.cs:line 23 at Core.Aspect.Validation.ValidationAspect.Before(IInvocation invocation) in C:\Users\atakan.gunay\source\repos\EReconcilationBackendProject\Core\Aspect\Validation\ValidationAspect.cs:line 40 at Core.Utilities.interceptors.methodInterceptors.Intercept(IInvocation invocation) in C:\Users\atakan.gunay\source\repos\EReconcilationBackendProject\Core\Utilities\interceptors\methodInterceptors.cs:line 21 at Castle.DynamicProxy.AbstractInvocation.Proceed() at Castle.Proxies.ICurrencyAccountServiceProxy.Add(CurrencyAccoundAddDto currencyAccoundAddDto) at EReconcilationUI.Controllers.CurrencyAccountController.Add(CurrencyAccoundAddDto currencyAccoundAddDto) in C:\Users\atakan.gunay\source\repos\EReconcilationBackendProject\EReconcilationUI\Controllers\CurrencyAccountController.cs:line 53 at lambda_method724(Closure , Object , Object[] ) at Microsoft.AspNetCore.Mvc.Infrastructure.ActionMethodExecutor.SyncActionResultExecutor.Execute(IActionResultTypeMapper mapper, ObjectMethodExecutor executor, Object controller, Object[] arguments) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.InvokeActionMethodAsync() at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.Next(State& next, Scope& scope, Object& state, Boolean& isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.InvokeNextActionFilterAsync()

Try error.message()

//or

let validationError = JSON.parse(err.text());
for (var fieldName in validationError) {
     if (validationError.hasOwnProperty(fieldName)) {
       this.error.push(validationError[fieldName]);
     }
}
