# Google Apps Script Specialist Debug Brief ## Project Overview A Google Sheets-bound Apps Script application for syncing custom values with GoHighLevel/LeadConnector CRM. The app has been successfully deployed via clasp CLI but requires debugging of UI-to-server function handlers. ## Current Status **WORKING:** - ✅ OAuth authentication flow completes successfully - ✅ Custom menus appear and function correctly - ✅ Sidebar UI displays and renders properly - ✅ Apps Script bound to target Google Sheet - ✅ All code deployed via clasp to correct script project **NOT WORKING:** - ❌ Sidebar button actions ("Save Location", "Connect to GHL") do nothing - ❌ Server-side handler functions not executing when called from UI - ❌ No execution logs appearing for UI-triggered functions ## Technology Stack ### Core Technologies - **Google Apps Script** (V8 runtime) - **Google Sheets** (bound project) - **HTML Service** (sidebar UI) - **OAuth 2.0** (Google Cloud Platform integration) - **GoHighLevel API** (REST API integration) ### Development Tools - **clasp CLI** (Google Apps Script command line tool) - **Google Cloud Console** (OAuth credential management) - **Node.js/npm** (local development environment) ## Skills Required ### Essential - **Google Apps Script expertise** (HtmlService, PropertiesService, server functions) - **OAuth 2.0 implementation** in Apps Script context - **JavaScript debugging** (client-server communication patterns) - **HTML/CSS/JavaScript** (frontend sidebar development) ### Helpful - **clasp CLI experience** - **GoHighLevel API knowledge** - **Google Cloud Platform** (OAuth setup and troubleshooting) - **REST API integration patterns** ## Project Structure ### Key Files - **Main.gs** - Primary server-side logic and menu handlers - **Config.gs** - Application configuration and OAuth settings - **Auth.gs** - Authentication and OAuth flow management - **LCAPI.gs** - GoHighLevel API integration - **SideBar.html** - Primary UI sidebar interface - **AdminPanel.html** - Admin configuration interface - **ConfigWizard.html** - Setup wizard interface ### Architecture Pattern - Server-side Apps Script functions (.gs files) - Client-side HTML/JavaScript interfaces (.html files) - google.script.run bridge for UI-to-server communication - PropertiesService for configuration persistence ## Problem Description The application successfully authenticates users via OAuth and displays the sidebar UI, but clicking buttons in the sidebar (such as "Save Location" or "Connect to GHL") produces no response. Server-side handler functions are not being executed when called from the client-side interface. ### Suspected Issues 1. **Function name mismatches** between client calls and server handlers 2. **Case sensitivity** in function references (recently bulk-renamed files/functions) 3. **Scope/authorization** issues preventing server function execution 4. **JavaScript errors** in client-side code blocking google.script.run calls 5. **File extension conflicts** (.js vs .gs after bulk conversion) ## Desired Outcome ### Primary Goal **Fully functional sidebar with working button handlers** that can: - Save location IDs to Google Sheets - Initiate OAuth connections to GoHighLevel - Execute API calls to sync custom values - Display success/error feedback to users ### Secondary Goals - **Error logging and debugging** setup for ongoing maintenance - **Code cleanup** from clasp deployment process - **Documentation** of final working configuration ## Access Requirements ### Required Access 1. **Google Sheets document** (edit permissions) - Target spreadsheet with bound Apps Script 2. **Apps Script project** (editor permissions) - Server-side code debugging and modification 3. **Google Cloud Console** (if OAuth troubleshooting needed) - OAuth credential verification 4. **GoHighLevel developer account** (if API testing required) - API endpoint and authentication testing ### Information to Provide - **Google Sheet URL** with bound Apps Script - **Apps Script Project ID** - **Current OAuth configuration** (CLIENT_ID, REDIRECT_URI) - **Error logs/screenshots** from recent testing - **Expected vs actual behavior** documentation ## Timeline Expectations - **Initial diagnosis:** 1-2 hours - **Fix implementation:** 2-4 hours - **Testing and documentation:** 1-2 hours - **Total estimated effort:** 4-8 hours ## Success Criteria 1. Sidebar buttons trigger server-side functions successfully 2. Execution logs show proper function calls and completions 3. API calls to GoHighLevel complete without errors 4. Data synchronization between Sheets and GoHighLevel works end-to-end 5. Error handling provides meaningful feedback to users ## Additional Context - This is a WordPress developer's side project for client CRM integration - Code was originally developed in a different environment and migrated via clasp - Recent bulk file renaming (.js to .gs) may have introduced function reference issues - OAuth flow works correctly, indicating proper Google Cloud setup - No sensitive data in scope - primarily configuration and API integration debugging
