"az keyvault secret list" throws "[Errno 22] Invalid argument" because there exists a bad certificate or secret in the vault

**Describe the bug**
I was using the following command: `az keyvault secret list`

This used to work, but one day the command stopped working and started throwing **[Errno 22] Invalid argument**.

One person suggested that my key vault might contain a bad secret with a bad expiration date. This was not exactly it, but apparently my vault did contain a bad _certificate_. I deleted a certificate, and now I could run `az keyvault secret list` again.

I cannot reproduce the certificate. But apparently certain data in the key vault can cause `az keyvault secret list` to crash.

**To Reproduce**
I cannot reproduce the certificate that caused the crash.

**Environment summary**
The crash happened with both version 2.27.1 and 2.30.0 of azure-cli, both on Windows.
