Autorest az 1.8.0 failing with TypeError: extension.updatePythonPath

[jjdharini22]

Hello,
I am trying to generate client libraries using the following command
autorest --az --version=3.0.6370 --azure-cli-extension='' --sdk-flatten <path-to-readme.md>

This fails with the following error.

AutoRest code generation utility [cli version: 3.6.2; node: v14.17.3]
(C) 2018 Microsoft Corporation.
https://aka.ms/autorest
info    | AutoRest core version selected from configuration: 3.0.6370.
   Loading AutoRest core      'C:\Users\djaiganesh\.autorest\@autorestcore@3.0.6370\nodemodules\@autorest\core\dist' (3.0.6370)
   Loading AutoRest extension '@autorest/az' (1.7.2->1.7.2)
   Loading AutoRest extension '@autorest/python' (5.4.0->5.4.0)
   Loading AutoRest extension '@autorest/clicommon' (0.6.1->0.6.1)
   Loading AutoRest extension '@autorest/modelerfour' (4.15.421->4.15.421)
TypeError: extension.updatePythonPath is not a function
Process() cancelled due to failure

I noticed this fails during the dependency installation of autorest/python 5.4.0.
I tried all the workarounds mentioned in some other issues like installing @autorest/python 5.4.0's dependencies in its virtual environment. But none of this seems to fix this issue.

I also tried older versions of az (1.7.0, 1.6.2), none of which worked.

Please let me know if there is some workaround that actually works. Or if there are any patch available?

Thanks
