Hi MindStudio Community, Iā€™m writing to report a critical and urgent bug that is preventing me from publishing a production-ready agent. My workflow, which relies on a hybrid model of scripts and LLMs, functions perfectly in the ā€œOpen Draft Agentā€ environment but fails immediately upon publication. This is a complete blocker for deployment. **The Core Problem:** The agent uses JavaScript `Run Function` blocks that require the **Virtual Machine** execution environment to import external libraries. While Iā€™ve configured this setting in my draft, the platform is automatically reverting the environment to **Sandbox** mode during the publishing process. This environment mismatch causes a fatal error: `Unexpected token 'export' [:` since the Sandbox environment does not support the `export` keyword used for module imports. **Additional Glitches:** Beyond the primary error, Iā€™ve observed other nodes returning `null` outputs in the published version, which function correctly in the draft. This points to a deeper issue with how the agentā€™s state is handled upon publishing, suggesting a critical bug in the platformā€™s deployment logic. This is an urgent matter as it makes my entire project unpublishable. **Steps to Reproduce:** 1. Create an agent with a `Run Function` block that uses an external library and an `export default` statement. 2. Set the `Run Function` environment to `Virtual Machine`. 3. Confirm the workflow runs successfully in ā€œOpen Draft Agentā€. 4. Publish the agent. 5. Execute the published agent. It will fail. I am ready to provide screenshots of the working draft execution and the failing published run logs to help with the diagnosis. I would greatly appreciate any immediate assistance or a workaround for this critical issue. Thanks, Satya.K ---
