Adding metadata to errors about error-or HOT 6 CLOSED

I personally would think that the easiest and most versatile solution would be to attach a simple dictionary to the error itself. Simple string as the key and an object as the value. My PR #37 could be used like this:

var metadata = new Dictionary<string, object>();
metadata.Add("id", 13947);

var error = Error.Failure("404", "entity not found", metadata);

Let me know what you think.

Different use cases:

1. environment metadata (helpful if the customer gives you only a screenshot of an error)
2. user context (session data, etc)
3. working with background APIs you may want to know which component is the real culprit (or if it was a resillience error)
4. compressed stacktrace, compressed binary log data

And this are only the ones on top of my head or ones I already have encountered.

Hmm, this is an interesting idea. What kind of metadata are we talking about? Is this a specific recurring object you want to attach to all errors? a string? Can you elaborate on the use case?

@amantinband Good evening. I was looking at using ErrorOr<> in our solution.
Currently, we use fluent validation with https://github.com/shanerogers/language-ext.

More specifically Result This is similar to your example (in docs) with mediatR with behaviours.

However, I also need meta-data used in our problem json responses. So this is also a blocker for me.
Also worth mentioning. Is it possible to have 'PropertyName' as a field? So each error can have the following:

• ErrorCode
• PropertyName
• Description
• ErrorType
• Metadata

I also find the Numeric type isn't something I need. Also, wondering how that works with 'Custom' types.

I would really need this

Added since I see many of you want this feature. Should be available in version 1.4.0 🙂
