Max allowed object depth reached while trying to export from type System.Guid

[EdisonHarada]

Hello,

I'm getting this error when I try to export an object that contains GUID. Probably is related to this other one: #11.

My code looks like this:

public void AddMetadata(KeyValuePair<string, object> metadata)
{
        AWSXRayRecorder.Instance.AddMetadata(metadata.Key, metadata.Value);
}

ThirdParty.LitJson.JsonException: Max allowed object depth reached while trying to export from type System.Guid

Hi @EdisonHarada ,
Sorry for delay in response. I looked into the issue and was able to reproduce it as well. We would probably need to write an exporter for the base class. I'll do some digging.
Meanwhile if your use case is adding only the Guid value as metadata, as a workaround you could use the ToString() method on the value.

Hi @EdisonHarada ,
Did the suggested workaround work for you?

I am closing this one and will add a feature task to our backlog to add the exporter for the base class for Guid. Feel free to reopen the issue if you need further discussion or anything else.

Thanks!

I'm adding my method inputs as metadata to segments, and I'm seeing this error for a new type, whenever I register an exporter for another. Can you add a simple ToString whenever WriteValue fails with this error? I believe this exception can't be caught and handled on the app side.
