Describe the bug
Error: parse error at (zookeeper/charts/common/templates/_secrets.tpl:82): function "lookup" not defined

To Reproduce
Deploy helm chart

Additional context
I just deployed yesterday and didn't have any issues. After getting this error, I forced version 6.0.0 of the Helm Chart and it worked. Not sure if something is wrong with the helm chart or if there are some breaking changes?
