Arvados

Workbench2 since v2.4.1 added arvados#workflow to the list of object types to include in its properties advanced search. The following is an example of filter passed to the controller:

[["groups.properties.IDTAGANIMALS","contains","IDVALANIMALS2"],["collections.properties.IDTAGANIMALS","contains","IDVALANIMALS2"],["container_requests.properties.IDTAGANIMALS","contains","IDVALANIMALS2"],["properties","exists","IDTAGANIMALS"],["uuid","is_a",["arvados#group","arvados#collection","arvados#containerRequest"]],["uuid","is_a",["arvados#group","arvados#containerRequest","arvados#collection","arvados#workflow"]]]

This generate an error message like: 422 Unprocessable Entity: #<NoMethodError: undefined method `type' for nil:NilClass>

An example of backtrace from ce8i5:

The workflows table doesn't currently have a properties column so it would seem that the code at record_filters.rb isn't handling this correctly.
