From 031350ec6b3d7c8775154246f544fb438a8f0718 Mon Sep 17 00:00:00 2001 From: Bas van den Aakster Date: Wed, 17 Sep 2025 19:06:09 +0200 Subject: [PATCH] fix: Address critical webhook and optimistic locking issues MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 🔒 Critical Fixes: - Implement proper optimistic locking with conflict detection and verification - Only register webhook endpoints when providers are properly configured - Move provider validation to initialization for early error detection - Fix TypeScript query structure for payment conflict checking 🛡️ Security Improvements: - Stripe webhooks only registered when webhookSecret is provided - Mollie validation ensures API key is present at startup - Prevent exposure of unconfigured webhook endpoints 🚀 Reliability Enhancements: - Payment update conflicts are properly detected and logged - Invoice updates only proceed when payment updates succeed - Enhanced error handling with graceful degradation - Return boolean success indicators for better error tracking 🐛 Bug Fixes: - Fix PayloadCMS query structure for optimistic locking - Proper webhook endpoint conditional registration - Early validation prevents runtime configuration errors 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- src/providers/mollie.ts | 15 +++++++++++--- src/providers/stripe.ts | 45 +++++++++++++++++++++++++++-------------- src/providers/utils.ts | 42 ++++++++++++++++++++++++++------------ 3 files changed, 71 insertions(+), 31 deletions(-) diff --git a/src/providers/mollie.ts b/src/providers/mollie.ts index 46fc7dd..b8d5440 100644 --- a/src/providers/mollie.ts +++ b/src/providers/mollie.ts @@ -38,10 +38,17 @@ export const mollieProvider = (mollieConfig: MollieProviderConfig & { webhookUrl?: string redirectUrl?: string }) => { + // Validate required configuration at initialization + if (!mollieConfig.apiKey) { + throw new Error('Mollie API key is required') + } + const singleton = createSingleton(symbol) return { key: 'mollie', onConfig: (config, pluginConfig) => { + // Always register Mollie webhook since it doesn't require a separate webhook secret + // Mollie validates webhooks through payment ID verification config.endpoints = [ ...(config.endpoints || []), { @@ -77,7 +84,7 @@ export const mollieProvider = (mollieConfig: MollieProviderConfig & { const status = mapMollieStatusToPaymentStatus(molliePayment.status) // Update the payment status and provider data -
