fix(ai-gateway): drop the Base44-App-Base-Url header path#222
Merged
Conversation
connection() now always builds the gateway baseURL from serverUrl (Base44-Api-Url inside backend functions). The backend PR that injected Base44-App-Base-Url was closed, so the header never ships; the platform instead guarantees Base44-Api-Url resolves to the app on every invocation path. Removes the header read in createClientFromRequest, the appBaseUrl plumbing into the AI gateway module, and the related tests. The pre-existing appBaseUrl client config (auth login/logout URLs) is unchanged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

What
Removes the
Base44-App-Base-Urlmechanism introduced in #214, before any release ships it (aiGatewayis still unpublished — latest npm is 0.8.35):createClientFromRequestno longer reads theBase44-App-Base-UrlheaderappBaseUrl;connection()builds itsbaseURLfromserverUrlonly (i.e.Base44-Api-Urlinside backend functions)appBaseUrl-preference tests; kept coverage for building fromBase44-Api-UrlThe pre-existing
appBaseUrlclient-config option (auth login/logout redirect URLs) is untouched.Why
The apper PR that would have injected
Base44-App-Base-Urlinto function invocations (base44-dev/apper#14868) was closed — the header will never exist on real invocations, so the SDK reading it is dead code.Verified live instead that
Base44-Api-Urlalready resolves to an app-recognized domain on the invocation paths that matter — published app traffic (same-origin), sandbox editor preview (preview-sandbox--{app_id}.*hosts are domain-resolved), and background workflows/automations (app-domain fallback) — soserverUrlis the right gateway origin. The one remaining gap (the builder's in-process test-function tool passes the builder host) is being fixed on the platform side, not in the SDK.Tests
