After updating our Okta integration to use the new OIDC connector, none of our 200 agents can log in. This is a P1 for us.

This is critical — I'm looping in our integrations team right now. Can you share your Okta tenant URL and the error message you're seeing?

Tenant: acme.okta.com. Error: 'invalid_client — The client_id is not valid.' We triple-checked the client ID.

Our integrations engineer found it — the new OIDC connector requires the client ID to be URL-encoded when it contains special characters. Your client ID has a '+' character. We're pushing a hotfix that handles this automatically. ETA 30 minutes.

Hotfix is live. Can you try logging in again?

Working! All 200 agents are back online. Please add URL-encoding to your setup docs.
