The OBJECTID field type is not set correctly

[jkerr5]

When generating a layer descriptor response using field metadata from a provider, OBJECTID fields are set to type esriFieldTypeInteger.

My provider is setting the field type for the OBJECTID field to "Integer" and this results in a the type in the layer descriptor response to be esriFieldTypeInteger. If I do not include field metadata for OBJECTID, koop sets it to the correct type of esriFieldTypeOID.

Is there a type that the provider should specify in the metadata to indicate that the field is an OID?

Would you please post the full provider response, including metadata? It's ok to truncate the features array.

This is a request for the layer resource so there is no features array. The URL requested is

/GDeltGKG/FeatureServer/0

The provider response is

If there is a type I should be setting in the metadata for OBJECT that would result in its type being set to esriFieldTypeOID in the koop response, please let me know.

[jkerr5]

In looking at a stack trace from another error, I happened to notice a typo in some winnow code. See line https://github.com/FeatureServer/winnow/blob/master/src/options.js#L38. Note the typo on the check for metadata.idFIeld.

I'm not sure if it's related to this but thought I would pass along anyway.

Fixed in winnow@1.10.6
