Firebase Email Template Personalizer (Cloud Function Automation)

**Firebase Email Template Personalizer (Cloud Function Automation)**

Project Description

Hello everyone,

I am facing an issue when trying to update or send email templates in my project. I keep receiving an error, and I am not sure what is causing it.

Details:

* Platform: Firebase / Node.js (or specify your stack)
* Issue: Error while updating or sending email templates

What I have already tried:

* Checked configuration
* Verified template settings
* Tried different approaches, but the issue still persists

I am looking for an experienced developer who can:

* Debug and fix the issue
* Explain the root cause
* Suggest a better and more scalable solution

Please contact me if you have experience with email systems, Firebase, or backend debugging.

Thank you
