Opencode Zen Bug: Muse Spark Models Fail on Images and Tool Calls with encrypted_content Error
pompompur-in · ghdev · 2026-09-13
A GitHub issue (#48741) filed against anomalyco/opencode reports that any Muse Spark model routed through Opencode Zen fails whenever an image is attached or a tool call (e.g., reading a file) is triggered. The upstream provider returns invalidrequesterror: reasoning encryptedcontent was not issued to this caller. Reproduced on Windows 11 25H2 with Windows Terminal on OpenCode 0.0.0-beta-18050, no plugins involved. As of now there is no official response (0 reactions, 3 comments), and the bug affects the entire Muse Spark family's multimodal and tool-calling capabilities on Zen.
