Steps to Reproduce

1. terraform plan

Expected Behavior

• Should show plan for the helm_release

Actual Behavior

• Provider panic

Important Factoids

• helm_release started to crash when dependency_update = true was added
• running in GKE
• the helm_release is defined in a module that is later on used by another module (maybe this does matter idk)
