Implement webhook, cron, and Telegram event triggers - #6
Conversation
Introduce Webhook (POST /webhooks/:id), Cron (scheduled handler), and Telegram Event (message, edited_message, etc.) trigger nodes. Update workflow validation and schema to accept new trigger types. Pass trigger payloads to the executor for dynamic value interpolation. Co-authored-by: aethelred-agent-factory <238771426+aethelred-agent-factory@users.noreply.github.com>

The
if/elsehere never throws: a non-200 response just logs "acceptable" and the suite proceeds either way. This is the only test exercising the scheduled-cron layer described in this PR's objectives, but it doesn't assert that cron matching actually happened or that trigger data was dispatched.Separately,
/__scheduledexposes a /__scheduled fetch route which will trigger a scheduled event (Cron Trigger) for testing during development, but only when wrangler dev is started with--test-scheduled— worth confirming the dev server spawn (not shown in this diff) passes that flag, otherwise this always 404s.

📐 Maintainability & Code Quality | 🟠 Major | ⚡ Quick win
Reuse getWorkflowObj instead of half-duplicating it here.
This block re-implements workflow/node loading with a reduced field set (SELECT id, type, config only, hardcoded position: {x:0,y:0}, no inputs/outputs), while the getWorkflowObj(env, id) helper added later in this same file (lines 1116-1160) already does this correctly and completely, including position_x/position_y, inputs, and outputs. Because getWorkflowObj is a hoisted function declaration, it can be called from here even though it's defined further down.

Use timingSafeEqual for the webhook secret comparison.
config.secret === querySecret || config.secret === headerSecret is a plain string comparison. This same file already avoids this exact pitfal for the Telegram webhook secret via timingSafeEqual (line ~616) specifically to prevent timing attacks. Since /webhooks/:workflowId is explicitly the public, unauthenticated endpoint, this comparison is the more exposed one and should use the same helper.

- if (config.secret === querySecret || config.secret === headerSecret) {

Webhook secret leaks back into trigger_data.headers/query.
headers: Object.fromEntries(request.headers.entries()) and query: Object.fromEntries(url.searchParams.entries()) capture the raw incoming request verbatim — including the X-Webhook-Secret header and/or ?secret= query param used to authenticate this very request. This payload is dispatched to GitHub Actions (client_payload.trigger_data) and later becomes node outputs in the execution log (scripts/executor.js lines 205-218), so the secret ends up persisted in GitHub Action run history and D1 execution logs, and can be re-exposed downstream if a notify/http node interpolates {{nodes.trigger.outputs.headers...}}.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Don't block the Telegram webhook response on trigger matching.
This awaits handleTelegramEventTriggers synchronously on every single incoming Telegram update (not just confirm/cancel), even for plain /whoami or arbitrary text messages that previously required no DB work at all. Internally it does several sequential D1 round trips per matched workflow (getWorkflowObj alone issues 3 queries) plus an un-timed fetch to the GitHub API in dispatchWorkflow when a match is found — all before the Telegram webhook response is returned. This adds unnecessary latency/timeout risk to the whole bot, unrelated to the message actually being handled. Since ctx is already available in fetch(request, env, ctx), this should run out-of-band via ctx.waitUntil (matching the pattern already used for the scheduled handler at line ~694).
⚡ Proposed fix
- if (env.DB) {
- try {
- await handleTelegramEventTriggers(env, update, request.url);
- } catch (err) {
- console.error("Telegram event trigger error:", err);
- }
- }
+ if (env.DB) {
+ ctx.waitUntil(
+ handleTelegramEventTriggers(env, update, request.url).catch((err) => {
+ console.error("Telegram event trigger error:", err);
+ })
+ );
+ }Separately, consider adding a D1 index on nodes(type) (and/or nodes(workflow_id, type)) since this query now runs on every inbound Telegram update.

🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win
matchField fails open (matches everything) on any unparseable field value.
In the no-dash, no-slash branch, if rangePattern doesn't parse as an integer (e.g. a typo, or month/day names like "JAN"/"MON", which are common in crontab-style syntax and aren't rejected by the schema), single is NaN and the if (!isNaN(single)) block is skipped entirely — leaving start = min, end = max from the outer defaults. Execution then falls through to return (val - start) % step === 0, which is always true for step defaulting to 1. So an invalid field silently becomes a wildcard instead of never matching — the opposite of a safe failure mode, and it can cause a cron trigger to fire far more often than the user configured (e.g. "0 0 1 JAN *" intended for once a year would fire on the 1st of every month).
🐛 Proposed fix
} else {
const single = parseInt(rangePattern, 10);
- if (!isNaN(single)) {
- if (step === 1) {
- return single === val;
- }
- start = single;
- end = max;
- }
+ if (isNaN(single)) return false;
+ if (step === 1) {
+ return single === val;
+ }
+ start = single;
+ end = max;
}Separately (lower priority): standard cron semantics treat day-of-month and day-of-week as OR'd when both are restricted (not *), but this implementation ANDs all five fields unconditionally. Combined with the lack of month/day-name support, consider a well-tested cron parser (e.g. cron-parser) instead of the hand-rolled implementation, given how many edge cases full cron syntax has.

This pull request implements the requested trigger mechanisms: Webhook trigger nodes (unauthenticated public POST endpoints supporting optional secrets), Cron schedule trigger nodes (run via Cloudflare Worker scheduled events), and Telegram Event trigger nodes (run via Telegram updates). All trigger payloads, headers, query parameters, or cron data are passed to the executor and made available as outputs for downstream value interpolation. Complete integration tests and validation scripts have been updated and verified successfully.
