Bug type

Regression (worked before, now fails)

Beta release blocker

No

Summary

I upgraded from 2026.4.22 to 2026.5.6. Cloudflare AI Gateway no longer works. When I attempt to chat with the bot I get this error in the chat:

Something went wrong while processing your request. Please try again, or use /new to start a fresh session.

This error shows up in the logs:

13:43:06+00:00 error diagnostic {"subsystem":"diagnostic"} lane task error: lane=main durationMs=1295 error="FailoverError: HTTP 401 authentication_error: x-api-key header is required" 13:43:06+00:00 error diagnostic {"subsystem":"diagnostic"} lane task error: lane=session:agent:main:main durationMs=1295 error="FailoverError: HTTP 401 authentication_error: x-api-key header is required"

My provider config remains unchanged.

"providers": {
  "cloudflare-ai-gateway": {
    "baseUrl": "https://gateway.ai.cloudflare.com/v1/CG_ACCOUNT_ID/CF_AIG_ID/anthropic",
    "apiKey": "${ANTHROPIC_API_KEY}",
    "api": "anthropic-messages",
    "headers": {
      "cf-aig-authorization": "Bearer ${CF_AIG_TOKEN}"
    },
