Just override the relevant localization strings.

For example, for internal server error message, you need to override InternalServerErrorMessage localization string. You can find the relevant localization keys here.

I tried with below code and the exception is not going through this class. My requirement not to just change localization string , need to change few things here

[Dependency(ReplaceServices = true)]
[ExposeServices(typeof(IExceptionToErrorInfoConverter), typeof(DefaultExceptionToErrorInfoConverter), typeof(CustomExceptionToErrorInfoConverter))]
public class CustomExceptionToErrorInfoConverter : DefaultExceptionToErrorInfoConverter
{
 // CODE
 }

It worked when i made below changes

[Dependency(ReplaceServices = true)]
[ExposeServices(typeof(IExceptionToErrorInfoConverter), typeof(DefaultExceptionToErrorInfoConverter), typeof(CustomExceptionToErrorInfoConverter))]
public class CustomExceptionToErrorInfoConverter : DefaultExceptionToErrorInfoConverter
{
// Code
}

to

public class CustomExceptionToErrorInfoConverter : : IExceptionToErrorInfoConverter, ITransientDependency
{
// Code
}

Please explain why is it so, this should work with Dependency and ExposeServices Attributes right and this is working with out those?

Glad it worked after recent changes 🥳

In response to your question, the code that shows how to override an example method like the one below should work.

[Dependency(ReplaceServices = true)]
[ExposeServices(typeof(DefaultExceptionToErrorInfoConverter), typeof(IExceptionToErrorInfoConverter))]
public class CustomExceptionToErrorInfoConverter : DefaultExceptionToErrorInfoConverter
{

    protected override RemoteServiceErrorInfo CreateErrorInfoWithoutCode(Exception exception, AbpExceptionHandlingOptions options)
    {
        // code
    }

}
