Hello Vercel Community,
I’m encountering a persistent issue with my Next.js application using Vercel KV for user registration. Despite following the documentation and implementing several debugging steps, I’m still unable to resolve this problem.
Issue:
When attempting to register a new user, I receive a “Database operation failed” error. The client-side error message is:
Steps taken:
- Verified all required environment variables are set (KV_URL, KV_REST_API, KV_REST_API_TOKEN, KV_REST_API_READ_ONLY_TOKEN).
- Implemented detailed server-side logging in the registration API route.
- Created a debug endpoint to test Vercel KV connection.
- Checked Vercel logs for any error messages during registration attempts.
Relevant code:
Registration API route (app/api/auth/register/route.ts):
import { NextResponse } from "next/server"
import { hash } from "bcryptjs"
import { kv } from "@vercel/kv"
export async function POST(request: Request) {
console.log("Registration route called")
try {
const body = await request.json()
console.log("Request body:", JSON.stringify(body))
const { name, company, email, password } = body
if (!name || !company || !email || !password) {
console.log("Missing required fields")
return NextResponse.json({ message: "All fields are required" }, { status: 400 })
}
try {
console.log("Checking if user already exists")
const existingUser = await kv.get(`user:${email}`)
console.log("Existing user check result:", existingUser)
if (existingUser) {
console.log("Email already exists")
return NextResponse.json({ message: "Email already registered" }, { status: 400 })
}
console.log("Hashing password")
const hashedPassword = await hash(password, 10)
const newUser = {
name,
company,
email,
password: hashedPassword,
}
console.log("Attempting to save new user")
await kv.set(`user:${email}`, JSON.stringify(newUser))
console.log("User registered successfully:", JSON.stringify(newUser))
return NextResponse.json({ message: "User registered successfully" }, { status: 201 })
} catch (dbError) {
console.error("Database operation error:", dbError)
return NextResponse.json({
message: "Database operation failed",
error: dbError.toString(),
stack: dbError.stack
}, { status: 500 })
}
} catch (error) {
console.error("Unhandled registration error:", error)
return NextResponse.json({
message: "Internal server error",
error: error.toString(),
stack: error.stack
}, { status: 500 })
}
}
