## Describe the problem/error/question I am trying to use the Graphql node to send queries/mutations to shopify but keep getting errors. I have even tried copying exactly from n8n templates, but keep getting the error message. ## What is the error message (if any)? TypeError: \_a.map is not a function at Object.execute (/usr/local/lib/node\_modules/n8n/node\_modules/n8n-nodes-base/dist/nodes/GraphQL/GraphQL.node.js:462:101) at processTicksAndRejections (node:internal/process/task\_queues:95:5) at Workflow.runNode (/usr/local/lib/node\_modules/n8n/node\_modules/n8n-workflow/dist/Workflow.js:725:19) at /usr/local/lib/node\_modules/n8n/node\_modules/n8n-core/dist/WorkflowExecute.js:673:51 at /usr/local/lib/node\_modules/n8n/node\_modules/n8n-core/dist/WorkflowExecute.js:1085:20 ## Please share your workflow ## Information on your n8n setup - **n8n version:** I have tried the node both on a cloud hosted version of the software, and on my own self hosted version. The self hosted version uses all default settings and is hosted on Digital Ocean. I get the same error on both instances. ---

It looks like your topic is missing some important information. Could you provide the following if applicable. - **n8n version:** - **Database (default: SQLite):** - **n8n EXECUTIONS\_PROCESS setting (default: own, main):** - **Running n8n via (Docker, npm, n8n cloud, desktop app):** - **Operating system:** ---

Welcome to the community @Ben_Vainer 🎉 I think the error you’re seeing occurs when you try to call `.map()` on something that isn’t an array. Can you try changing the `files` input into an array instead of an object in the variables? ```auto { "files": [ { "alt": "Ben", "contentType": "IMAGE", "filename": "Ben", "originalSource": "https://teecommercecabot.myshopify.com/cdn/shop/files/CH_Spire_180x180_4824f432-59d0-4010-8826-e39b637c2eb1_110x.png?v=1721942398" } ] } ``` ---
