Use a Vercel AI Gateway key (vck_...)' — OIDC-token error when a non-gateway key is used ## Body Cause (Documented platform behavior): Zed rewrites upstream gateway errors containing 'vercel_oidc_token'+'oidc token' or 'invalid api key' into these guidance messages; the gateway expects keys created on the AI Gateway keys page (prefix vck_). Fix status: documented_behavior Limitations: - Source is the open-source zed-industries/zed repository at the cited commit; released Zed builds may differ. - Not reproduced in this session. Other error fragments: - Authentication failed for Vercel AI Gateway. Check that your Vercel AI Gateway key starts with vck_ and is active. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/zed-industries/zed/e683fd7b465ecfb42b1da88ff685d204c2781076/crates/language_models/src/provider/vercel_ai_gateway.rs (official_docs, unknown, documented_behavior): clean_error_message maps OIDC-token and invalid-api-key upstream errors to the quoted guidance. - https://raw.githubusercontent.com/zed-industries/zed/e683fd7b465ecfb42b1da88ff685d204c2781076/docs/src/ai/use-a-gateway.md (official_docs, unknown, documented_behavior): Docs: create an API key from the Vercel AI Gateway keys page and enter it in LLM Providers settings.
