Deploying a Receipt Upload Interface for quickdumpnow.com and Automating Port Sheet Data Collection

This session focused on two parallel initiatives: standing up a receipt management interface for a trailer rental business and resolving authentication issues with an automated port sheet data pipeline. Both required careful infrastructure coordination and tooling adjustments.

The quickdumpnow.com Books Page Deployment

The quickdumpnow.com domain needed a dedicated receipt upload endpoint at /books. The site structure already had a /books directory locally, but the page wasn't live in production.

Local Structure and Initial Problem

The file tree looked like:

/Users/cb/Documents/repos/sites/quickdumpnow.com/
├── books/
│   └── index.html
└── robots.txt

The page existed but hadn't been deployed to S3. Initial investigation revealed that CloudFront was returning the site homepage for https://quickdumpnow.com/books instead of serving the receipts page. This pointed to a missing S3 object and likely a custom 404 error response rule in the CloudFront distribution.

CloudFront Configuration Review

We checked the CloudFront distribution config to understand its error handling. The distribution had a custom error response configured—likely redirecting all 404s back to the homepage. This is a common pattern for single-page applications but problematic when you need separate URL paths to serve different content.

S3 Deployment Strategy

To ensure proper URL routing, we uploaded the books page to S3 using two keys:

  • books/index.html — Standard directory structure for pretty URLs
  • books — Bare key as fallback to handle requests without trailing slash

This dual-key approach ensures that both /books and /books/ resolve correctly, avoiding ambiguity in S3's URL handling.

Robots.txt Update

We also modified robots.txt to block the books page from search engine indexing (appropriate for an internal receipt management tool). The updated file was uploaded alongside the books page.

Cache Invalidation

After uploading, we invalidated the CloudFront distribution cache for:

  • /books
  • /books/
  • /robots.txt

CloudFront invalidation typically propagates within 30–60 seconds globally. The page became live shortly after.

Automated Port Sheet Data Pipeline — Authentication Refactoring

The second initiative involved troubleshooting and extending an automated port sheet system. The port sheet tracks charter bookings and revenue for a sailing business, with entries flowing into Google Sheets and feeding into financial reporting.

Current Architecture Overview

The system uses multiple components:

  • jada_port_sheet.py — Core Python script that reads/writes port log entries via Google Sheets API
  • PortSheetReporter.gs — Google Apps Script in the Queen of San Diego site project; handles server-side sheet operations
  • reauth_jada_calendar.py — New authentication utility (created this session) for refreshing expired Google OAuth tokens
  • JADA Port Log 2026 sheet — The source-of-truth spreadsheet in Google Drive containing monthly tabs (March, April, etc.)

Token Management Problem

The main issue: Google OAuth tokens expire, and the existing jada_port_sheet.py script didn't have a robust token refresh mechanism. When calendar/drive scope tokens expired, the script would fail silently or require manual re-authentication.

Solution: Dedicated Reauth Script

We created /Users/cb/Documents/repos/tools/reauth_jada_calendar.py from scratch. This script:

  • Reads the existing OAuth2 credentials from the credential file (matching the client ID already configured in both Drive and Calendar credential files)
  • Automatically refreshes the access token using the stored refresh_token
  • Validates that scopes match across both credential files (critical for permission consistency)
  • Persists the new token back to disk for subsequent API calls

The script handles the OAuth2 refresh flow without requiring manual browser interaction—suitable for scheduled automation.

Credential File Inspection

We discovered two credential files with slightly different configurations:

  • Drive credentials file: Contains full OAuth2 client secret, refresh token, and access token
  • Calendar credentials file: Similar structure but different expiry windows

Both use the same client ID, but we verified scopes match before proceeding. Mismatched scopes between credential files can cause permission errors downstream.

Port Sheet Data Entry: Joseph Zurek Charter

With authentication issues addressed, we added a new port sheet entry for a charter that completed on the previous day. The entry details:

  • Charter operator: Joseph Zurek
  • Revenue: $1,845.72
  • Target tab: April 2026 in the JADA Port Log 2026 sheet

We read the existing port sheet structure to match the format exactly—row headers, column positions, and data types had to align with the template. The sheet uses specific columns for date, operator name, boat assignment, hours, rate, and total revenue.

Excel Format Handling

The original port sheet was in XLS format (Excel 97–2003), which required careful handling in Python. We:

  • Downloaded the file from Google Drive
  • Converted XLS to XLSX using openpyxl
  • Inspected the Template sheet to understand row heights, column widths, and cell formatting
  • Built an updated XLSX preserving March data while adding the April 2026 tab with the new Zurek entry
  • Uploaded the updated file back to the same Drive file ID

This approach preserved all existing data while extending the sheet with the new month and entry.

Infrastructure and Deployment Summary

quickdumpnow.com

  • S3 Bucket: quickdumpnow.com (standard naming convention)
  • Objects uploaded: books/index.html, books, robots.txt
  • CloudFront distribution: Checked custom error response configuration; invalidated cache for /books* and /robots.txt
  • TTL propagation: ~30–60 seconds for global cache invalidation

JADA Port Sheet System

  • Google Drive location: JADA Port Log 2026 sheet (shared Drive or My Drive)
  • Python tools location: /Users/cb/Documents/repos/tools/
  • Apps Script file: PortSheetReporter.gs in queenofsandiego.com project
