User receiving an error when using the API to run a Query for AttributeDefinition - Not able to parse artifact type: attributedefinition

Products

• Rally SaaS

Issue/Introduction

The attributedefinition and typedefinition objects appear to be of identical categories in the wsapi documentation.  I can query a typedefinition, but not an attributedefinition.  If in each case I supply a Name = blah argument, I get a not-found response with typedefinition, but I get a “Not able to parse artifact type: attributedefinition” response with attributedefinition.

My goal is to get a list of the allowed values of an attribute, given the name of the attribute.

Environment

Resolution

AttributeDefinition is not queryable, whereas the TypeDefinition is.  

Below, you can see that the WSAPI documentation shows a query is available for TypeDefinition:

But in the next screenshot you can see that there is no query available for AttributeDefinition:

It is possible to read (not query) an AttributeDefinition if you have the AttributeDefinition ObjectID using the following URL (as seen above)
