Experience
Sitecore XM Cloud Self-driven POC Project with Agentic AI Workflows
https://github.com/mystackdevnode/xmcloud-starter-js/blob/main/tutorial_xmCloud_local_setup.mdBuilding upon the Sitecore Foundation project, I have included my own XM Cloud Troubleshooting and Deployment Guide. This repository provides key solutions for resolving common local environment issues, such as locked-out accounts, broken PowerShell elevation prompts, and Next.js SSL errors. Additionally, it outlines the steps required for successfully deploying a local site to XM Cloud.
The guide meticulously documents the necessary steps and fixes to run the local Sitecore XM Cloud JSS environment correctly on a Windows VM.
