Hi @kurayami07734, thanks a lot for taking the time to raise this PR. We've included the changes in our latest release (#100). The field list: List[ListEntitlementResponse] should have been list: List[CreateEntitlementResponse], as the list and create responses may diverge in the future. This has been corrected by our SDK generator in the subsequent PR. Apologies for the delayed response.
