Problem with a shopify app causing items to show £0

I have a swimwear company and use shopify. I have an app called 'Shop the look' which I have had for about 5 years plus without any problems. I have lots of 'looks' set up on here and the matching bikin itemi is shown on the product page, i.e. matching bikini bottom for the bikini top. However all of a sudden the prices for the matching items now show £0. If i delete and re-add the items on the app it does show the correct price for a few hours but then it reverts to £0. It seems to only show £0 for some items not all. This is causing me a lot of stress as it is currently my peak season for swimwear. I really need this urgently fixed so the prices display correctly.

Creation of an AI agent for Claude (Opus 4.8)

Build an AI Web & WhatsApp Chatbot (Node.js + Claude API) We're a company looking for an experienced developer to build a customer-facing AI chat assistant powered by Anthropic's Claude API, running on both our website and WhatsApp Business. The assistant answers visitor questions using content drawn exclusively from our own website, captures contact details, and emails each completed conversation to our team so they can follow up. This is a self-contained, end-to-end build with clear, documented deliverables. Scope of work: A Node.js + Express backend that calls the Claude API, keeping the full conversation server-side and never exposing credentials to the browser. A lightweight, embeddable web widget: a floating launcher that invites visitors to ask, a branded chat panel, a custom agent name and logo, and a welcome message. A WhatsApp Business integration through Meta's official Cloud API: webhook verification, message send/receive, and per-user session handling, reusing the same core logic as the web agent so both channels behave consistently. A retrieval-augmented (RAG) layer that crawls our sitemap on a nightly schedule, indexes the entire site, and grounds every answer in that content, with strict anti-hallucination rules that direct users to a contact address when information isn't available. Automatic email delivery of each transcript through our SMTP server (Postfix, SSL) on both channels, sent when a conversation finishes. Spam and abuse protection: rate limiting, honeypot fields, input validation, and a configurable daily cost cap to protect the API budget. Requirements: strong JavaScript/Node.js, solid experience with REST APIs and LLM integration, familiarity with embeddings and RAG pipelines, the WhatsApp Business Cloud API, SMTP configuration, and sound security practices. GDPR awareness is a plus. Deliverables: production-ready, documented code with full setup instructions. Generic placeholders are provided for all company-specific values, so configuration is straightforward. Please send a brief proposal, relevant work samples, and your estimated timeline and budget.
