[ArcturusZhang]

I am generating api.yaml file using autorest.cli with input file: azure-rest-api-specs\specification\policyinsights\resource-manager\readme.md

Tag in use

package-2019-10.

Cli section added in readme.md

cli:
  cli-name: policyinsights
  azure-arm: true
  license-header: MICROSOFT_MIT_NO_VERSION
  namespace: azure.mgmt.policyinsights
  package-name: azure-mgmt-policyinsights
  test-scenario:
    - name: Query latest at management group scope

Problem encountered

An error is reported as follows:

ERROR: ERROR RangeError: Maximum call stack size exceeded

I am suspecting that the function GetModelOptions is nested to much levels.

This happens when swagger contains some recursive data types, such as trees.
