Various code generators, such as https://openapi-generator.tech , do not generate an API client because there are errors in the API description: -attribute paths. ' /auth/saml/ {samlProviderId} /acs' (post) .operationId is repeated -attribute paths. ' /auth/saml/ {samlProviderId} /login' (post) .operationId is repeated It seems that there are also problems with the DraftTask as it is ambiguous.
