Missing arguments: webhook.id, webhook.url, applicationId/se

Error message

Missing arguments: webhook.id, webhook.url, applicationId/serviceName

What it means

WebhookController.updateWebhook validates that the PUT body supplies a webhookId, a url, and an application identity (applicationName or serviceName). If any of these is missing/empty, it throws HTTP 400 before performing URL validation or the update, since an update without the id cannot target a row and without url/application binding would be meaningless.

Solutions

1. Send the complete Webhook object: webhookId, url, and either applicationName or serviceName all non-empty
2. Fetch the current webhook via GET /webhook and merge your change before PUTting it back
3. Verify URL starts with a valid scheme since validateURL runs immediately after this check
4. Confirm JSON key names/casing match the Webhook DTO fields

Example fix

// before
{"webhookId":"abc123","url":"https://hooks.example.com/x"}
// after
{"webhookId":"abc123","url":"https://hooks.example.com/x","serviceName":"myService"}

function canUpdateWebhook(w) { return Boolean(w && w.webhookId?.trim() && w.url?.trim() && (w.applicationName?.trim() || w.serviceName?.trim())); }

function isCompleteWebhook(w) { return typeof w.webhookId === 'string' && w.webhookId.length > 0 && typeof w.url === 'string' && w.url.length > 0 && (typeof w.applicationName === 'string' || typeof w.serviceName === 'string'); }

try { await api.updateWebhook(body); } catch (e) { if (e.response?.status === 400 && e.response?.data?.message?.includes('Missing arguments')) { /* re-fetch webhook and merge full object */ } throw e; }

When it happens

Trigger: PUT /webhook with body missing webhookId, missing url, or missing both applicationName and serviceName; empty-string values also trigger it; wrong key casing leaves the POJO fields null.

Common situations: Clients echoing back a webhook object read from an API variant that omits url; partial-update attempts sending only changed fields (the API requires full object); renames where serviceName was dropped from the payload.
