Failed to generate postgresqlhsc az client

[furkansahin]

I am trying to generate an az extension code via autorest by running the following command from wsl2;

autorest --az --input-file="./azure-rest-api-specs/specification/postgresqlhsc/resource-manager/Microsoft.DBforPostgreSQL/preview/2020-10-05-privatepreview/postgresqlhsc.json" --azure-cli-extension-folder=./azure-cli-extensions --sdk-no-flatten --verbose

However, it fails with the following error;

FATAL: TypeError: Cannot read property 'replace' of undefined
WARNING: [autorest.codegen._get_credential_param:151] You have default credential policy BearerTokenCredentialPolicybut not the --credential-scopes flag set while generating non-management plane code. This is not recommend because it forces the customer to pass credential scopes through kwargs if they want to authenticate.
  Error: Plugin azentry reported failure.

Here is the full verbose output

I have tried autorest --reset but no luck. Can you please help me understand what is wrong?
