Scope/collection not found errors not being parsed on CC

Testing against: Couchbase 7.0.0-4554 onwards (at least)
Have seen collection manager regressions due to ScopeNotFound and CollectionNotFound errors not being used due to a parsing miss.
The server is returning 404's with the following content:

Scope not found:
{"errors":{"_":"Scope with name \"foobar\" is not found"}}

Collection not found:
{"errors":

{"_":"Collection with name \"0a8ccba8-9\" in scope \"8e92357b-3\" is not found"}

}
