yaml templates values "" are changed into null when published

[mikosa]

I have a spinnaker deploy step that deploys a kubernetes chart saved within (manifest source: text)
When I try to publish the pipeline template file the line under apiGroups with "" is replaced by "null" at one line and in the second line, apiGroups is deleted (because the value is null). But kubernetes chart requires the presence of apiGroups to work correctly, and value should be equal to ""

I tried different things including '', "", ~, [].... But was not able to get the needed ""
any ideas? or suggestions?
