Update: fixed now. Seems you have to completely uninstall autorest v2 and install v3 to make it work

I was trying to generate code using autorest but got an error

Error: Cannot resolve pipeline stage 'openapi-document/multi-api/identity'.

autorest 3.0.5532
autorest.powershell (beta->2.0.648)
autorest.remodeler (beta->2.0.374)
