Not sure where to report this so this forum will do.
There’s an error in the OpenAPI spec: in the definition for the UpdateFlowsVaultConnectionSetup type, the oneOf list has a duplicate for "$ref": "#/components/schemas/FlowsVaultConnectioSetupOauthCode", which throws off code generators.
In addition, there’s a typo in the names of theFlowsVaultConnectioSetupXXXtypes (missing the last “n” in “Connection”).
