Dream Hunter 1584851a36 docs: note that subdomains need Email Routing enabled separately (#970)
Subdomains do not inherit Email Routing from the apex domain;

General

Issue Solution
Sending emails to authenticated forwarding addresses using Cloudflare Workers Use CF's API for sending, only supports recipient addresses bound to CF, i.e., CF EMAIL forwarding destination addresses
Binding multiple domains Each domain needs to configure email forwarding to worker
Subdomain cannot receive email Subdomains must have Email Routing enabled separately on Cloudflare with their own DNS records and Catch-all rule. Enabling it only on the apex domain does NOT cover subdomains. See Email Routing
Issue Solution
Uncaught Error: No such module "path". imported from "worker.js" Reference
No such module "node:stream". imported from "worker.js" Reference
Subdomain cannot send emails Reference
Failed to send verify code: No balance Set unlimited emails in admin console or increase quota on the sending permission page
Github OAuth unable to get email 400 Failed to get user email GitHub user needs to set email to public
Cannot read properties of undefined (reading 'map') during page initialization First check whether /open_api/settings is returning valid data. In a direct Worker deployment, this usually means Worker variables were not configured correctly, so verify JSON-format variables such as DOMAINS and ADMIN_PASSWORDS. If this happens in a Pages deployment because requests are going to the wrong backend address, continue with the Pages troubleshooting section below
Issue Solution
network error Use incognito mode or clear browser cache and DNS cache
Pages deployment shows the map error, or API requests such as /admin/users / /admin/new_address return 405 Method Not Allowed This is usually caused by an incorrect frontend backend address. Check VITE_API_BASE, the URL entered when generating the zip in the UI guide, or FRONTEND_ENV: for separate frontend/backend deployment talking directly to Worker, it should be the backend Worker API root URL, start with https://, and have no trailing /; if you use PAGE_TOML to proxy backend requests through Page Functions, VITE_API_BASE can be left empty to use same-origin requests. See Pages Frontend Deployment
Refreshing page or directly visiting /admin, /user returns 404 This project is a Single-Page Application (SPA). When deploying Pages via UI, set "Not Found handling" to Single-page application (SPA) in the advanced options. See Pages Frontend Deployment
Issue Solution
Set DEFAULT_SEND_BALANCE but still getting No balance DEFAULT_SEND_BALANCE is the default quota when users request sending permission. Users must first click "Request Send Permission" in the frontend. Alternatively, add the address to the "No Limit Send Address List" in the admin console, or configure NO_LIMIT_SEND_ROLE
Error: Please enable resend or smtp for this domain You need to configure RESEND_TOKEN or SMTP_CONFIG first. See Configure Email Sending
SMTP_CONFIG configured but sending fails Make sure the JSON key is your own sending domain (e.g. your-domain.com), not the example awsl.uk. See Configure Email Sending
Issue Solution
Set ENABLE_ADDRESS_PASSWORD but Foxmail/Outlook cannot login ENABLE_ADDRESS_PASSWORD only enables the "address password login" web API. It does NOT provide standard IMAP/SMTP service. To use mail clients, you need to deploy the SMTP/IMAP Proxy Service

Telegram Bot

Issue Solution
Telgram Bot failed to get email: 400: Bad Request:BUTTON_URL_INVALID tg mini app URL is incorrect, should be the pages URL
Telegram bot bind error: bind adress count reach the limit Need to set worker variable TG_MAX_ADDRESS

Github Actions

Issue Solution
After Github Action deployment, CF always shows preview branch Go to CF pages settings to confirm that the frontend branch matches the Github Action frontend deployment branch
