Puppet rejects tasks with valid non-Data types like 'Hash'

Puppet Version: Bolt

Puppet Tasks can only accept parameters as JSON. However it should be valid in task metadata to use puppet types that may be assignable to JSON like bare Hash. Puppet seems to be rejecting these

Error: Failed to load metadata for task example_tasks::hash_get: Task initializer has wrong type, entry 'parameters' entry 'data' entry 'type' expects a Type[Data] value, got Type[Hash] in /Users/adreyer/src/puppetlabs/puppetconf_modules/example_tasks/tasks/hash_get.json

Desired Behavior:

Task metadata that gives parameters types that may be assignable to Data should be considered valid.

Actual Behavior:

Puppet refuses to load tasks that use types which are not assignable to Data like Hash
