#3926 regression: Self-signed certificates

Describe the bug See previously documented bug: #3341 For those of us behind a corporate proxy with self-signed certificates, we need a way to configure that. With the built-in yarn, there’s no clear way to do that.

Reverting to v3.1.1 works.

Expected behavior autorest should function behind a proxy.

Additional context #3341 Breaking change: #3926

Alternativel would be to remove the --no-default-rc to still use the global yarn config but use YARN_IGNORE_PATH=1 instead to prevent a different version of yarn from being loaded(Issue solved in #3926)

Could do this at least as a short term solution.

The suggestion in #3341 to install yarn separately worked for me, then I was able to issue the command yarn config set strict-ssl false -g to fix this error message:
