* [ruby|client] Fix unmarshalling errors of enums inside other objects
Ruby|Client autogenerated model classes for Enums do not expose openapi_one_of
method. Instead they expose openapi_any_of method like:
# List of class defined in anyOf (OpenAPI v3)
def openapi_any_of
[
:String
]
end
Both types (objects and enums) do respond to build() method.
* Regenerate samples
* fix setup of body params (may be nil)
* fix httpx adapter issues
treating DNS resolution errors as ConnectionFailed; removing multipart header set by the openapi-generated code, as it does not contain boundary, and interferes with the generation from httpx, which appropriately deals with mime-types already
