error_text_of

source
fn error_text_of(e :

Map an @http.HttpError into the BiDi errorText string that network.fetchError / network.responseCompleted payloads expose to the driver.

The two CORS variants get distinguishing prefixes so a Playwright / WebDriver client can tell a preflight rejection apart from the actual request being blocked:

  • CorsBlocked(reason) -> "CORS: <reason>"
  • PreflightFailed(reason) -> "CORS preflight: <reason>"

Existing variants retain their Show form so legacy callers see the same errorText as before.

Reason strings from CorsBlocked, PreflightFailed, and CorsError are sanitized via sanitize_for_log before interpolation to prevent log injection from malicious server-controlled values.

#
js_push_synthetic_navigation

source
fn js_push_synthetic_navigation(url : String) -> Unit

Push a synthetic-navigation marker onto the JS realm so the adapter's flushPendingNavigation can mirror it onto currentUrl on the next script.evaluate boundary. Used by server-side pointer-click navigation (input.performActions path), where the in-realm shim click() default action doesn't run. (#208)

#
js_set_runtime_context_authorization

source
fn js_set_runtime_context_authorization(ctx_id : String, auth_json : String) -> Unit

Push the per-context Authorization snapshot into the JS realm. The snapshot is consumed by the auto-installed globalThis.__bidiResolveAuth helper that the fetch shim calls before dispatching each outbound request. Mirror of set_runtime_context_cookies.

#
js_set_runtime_context_credentials

source
fn js_set_runtime_context_credentials(ctx_id : String, creds_json : String) -> Unit

Push the per-context Digest credentials snapshot into the JS realm. The snapshot shape is { origin: { username, password } }. Consumed by the fetch shim's 401 Digest auto-retry path via the auto-installed globalThis.__bidiResolveCredentials(url) helper.

Credentials are passed by-value into the JS realm — there is no indirection that would let the page read them ambient-style. The runtime-side helper only returns the matching entry for the request's origin AND only inside the retry path that already has a Digest challenge in hand, so an attacker page on a different origin can't silently extract a stored credential by issuing fetches.

#
js_set_runtime_prompt_handlers

source
fn js_set_runtime_prompt_handlers(handlers_json : String) -> Unit

Push the per-context unhandledPromptBehavior snapshot into the JS realm. Read by resolvePromptHandler inside alert/confirm/prompt to decide the synchronous return value. Snapshot shape mirrors the spec dictionary: { alert: "dismiss", confirm: "accept", prompt: "dismiss",default: "dismiss" }. Missing entries default to "dismiss".
fn navigate_and_send_async(socket : 
Any, request_id : Int, ctx_id : String, url : String, navigation_id : String) -> Unit

MoonBit wrapper around js_navigate_and_send_async. Used by the navigate dispatch when wait=complete is requested for an http(s) URL — instead of the broken sync sync_runtime_page() path, the JS body awaits the page load and emits the BiDi response via socket once the load resolves.
