Java deobfuscation seems broken

[phpn00b]

I have tried using the deobfuscate tool in the java bundle to upload a source map and every time the servers log shows the same error message along the lines of:
ArgumentError: syntax error on line 4, col -1: children: !ruby/object:Set

I also tried to directly load the source map via the rails console with the following

environment = 'production' build = '400023' api_key = '155268d7-f737-4550-9552-a231aa82e9f6' map = Squash::Java::RenameLog.new("../mapping.txt").parse project = Project.find_by_api_key(api_key) or raise(API::UnknownAPIKeyError) deploy = project.environments.with_name(environment).first!. deploys.find_by_build!(build) deploy.obfuscation_map.try! :destroy deploy.create_obfuscation_map!(namespace: map)

to no avail

How do I go about getting my android app's mapping.txt converted into a form that squash can use and loaded into the database so I can make full use of squash?
