How to fix Vercel 500 error with serverless functions

This is huge! We have just published the first release candidate for Serverpod 3, code-named "Industrial". 🚀 We've been working on this update over the past six months, and it includes some significant improvements. The largest new features are a much-improved web server based on Relic and a complete rewrite of the authentication module. You can find the full release notes here (there is a lot in it!): https://lnkd.in/dsWwKPN5

Found multiple file inclusion points and a few rabbit holes, but one led to remote code execution! I just finished the File Inclusion module on Hack The Box for the Web Pentester path 📁. While mapping and fuzzing, I found several inclusion points, and some led me down little rabbit holes that took extra time before I realized they were dead ends. I used the working ones to read source code in a few places, and curling the files helped me spot the filters in play. I also found an upload page where a PHP payload I uploaded was saved under an MD5 filename. Using a discovered inclusion point, I called the hashed file, enumerated the server from there, and tracked down the flag. Careful mapping with small pivots can turn reading files into real impact. Best practices for preventing file inclusion. Do not pass user input into include or file-read functions. Use a strict allowlist that maps inputs to approved server-side file paths, fall back to a safe default, and never include raw user input. Normalize and validate paths with built-in functions, strip traversal sequences recursively, and reject anything outside the allowed directories. Turn off remote file inclusion and URL wrappers, lock the app to its web root with open_basedir or containers, and run with least privilege. Keep sensitive config outside the web root, disable risky modules, log access to inclusion endpoints, and monitor for traversal patterns. Defense-in-depth is key. #AppSec #LFI #RFI #HackTheBox

WEB TECHNOLOGY Web technology refers to the tools, languages, and protocols that enable the creation, delivery, and interaction of websites and web applications over the internet. It involves a combination of front-end development (what users see and interact with, using languages like HTML, CSS, and JavaScript) and back-end development (server-side logic, databases, and infrastructure). Key components include web browsers, web servers, and communication protocols like HTTP.

Next.js 16 brings major developer experience improvements: ⚡ Turbopack is now stable → super-fast builds 🧠 use cache directive → smarter caching control 🧩 New proxy → replaces middleware for clarity ⚙️ Full React 19 support If you haven’t upgraded yet, it’s worth it. 🚀

🌐 𝐇𝐓𝐓𝐏 𝐒𝐭𝐚𝐭𝐮𝐬 𝐂𝐨𝐝𝐞𝐬 𝐘𝐨𝐮 𝐒𝐡𝐨𝐮𝐥𝐝 𝐊𝐧𝐨𝐰 Every web developer encounters them — those three-digit HTTP status codes that tell you what’s really happening between the client and server. Here’s a quick breakdown 👇 🔹 1xx – Informational: Request received, processing continues 🔹 2xx – Success: The request was successful 🔹 3xx – Redirection: The client must take additional action (like follow a redirect) 🔹 4xx – Client Error: The request has an error from the client side 🔹 5xx – Server Error: The server failed to fulfill a valid request These codes are defined in RFC 9110 — a 200-page read if you ever feel like diving deep 😅 To save you some time, here are some common examples: ✅ 200 OK – Everything’s good ✅ 201 Created – Resource successfully created ⚠️ 400 Bad Request – Invalid request syntax 🔒 401 Unauthorized – Authentication required 🚫 403 Forbidden – Access denied ❌ 404 Not Found – Resource doesn’t exist 🔥 500 Internal Server Error – Something went wrong on the server

Spawning Swarms in Claude Code Web using 🌊 Claude-Flow & Open Router/Gemini. Claude Code Web now supports connecting to third party services directly through env keys, letting me spawn and manage concurrent swarms using Claude Flow and Agentic Flow, all from within the browser or mobile app. No servers. No VS Code. Claude Flow runs locally so none of your data goes to any third party. It automatically obfuscates your API keys through a high speed Rust proxy running on localhost which means your keys are never shared with the LLMs. It is open source so you can verify exactly how it works and confirm that everything stays secure. Once your secrets are loaded run npx agentic flow npx claude flow@alpha npx agentdb Then spawn a five agent swarm to handle your task. Include your OpenRouter Gemini or other API keys in the env panel so the agents can connect through your configured proxy. Sample prompt /swarm “Using the Claude secrets, Please run npx agentic-flow and npx Claude-flow@alpha and npx agentdb and spawn a 5 agent swarm concurrently to fully implement the following …. Include tdd, review, fix, optimize, prepare to publish as a package.” Make sure to include your various openrouter keys etc. it seems pretty secure, but be safe. Limit your keys TIL, and create them just for these swarms. This also works with no keys at all.

Node.js v25.0.0 (Current) Released — The latest cutting edge version of Node has arrived with Web Storage enabled by default, JSON.stringify perf improvements, a new --allow-net option in the permission model, built-in Uint8Array base64/hex conversion, and WebAssembly and JIT optimizations. As shown in the diagram above, this means Node 24 will soon be promoted to being the 'active' LTS release and Node 22 will enter its 'maintenance' LTS phase by Rafael Gonzaga

Today, we’re announcing the launch of the Parallel Monitor API, the newest addition to our Web Agents API suite. Parallel Monitor can be thought of as a web search that’s always on: you define a query that kicks off an ongoing stream of updates every time new related information appears on the web. Instead of actively making a search for information, Parallel Monitor is passively watching the web for changes to notify you about. It’s available now to try for free in the Parallel developer playground. Read our blog for more information: https://lnkd.in/eh8UxgM4
