ibm_is_public_gateways_info modules fails with Unsupported argument "generation"

[indirakalagara]

When trying to fetch the gateways with just region specified, ansible playbook failed with error on unsupported arguments.
Even. though the generation field is not specified, looks like the terraform script is adding the field with default set to 2.

Playbook snippet:
- name: Fetch Public Gateway Details
ibm_is_public_gateways_info:
region: "{{region}}"
register: pgw_output

Error:
