Common ComfyUI errors and fixes. OOM, missing nodes, dtype mismatches, black images, and debugging strategies.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# ComfyUI Troubleshooting Guide > Render completes but looks WRONG (artifacts, wrong subject/pose/color, a > ControlNet/mask/LoRA not taking, a refiner degrading it)? That's not an error. > Use the debug-render skill (`list_packs` with `action: "skill_read"`, > `name: "debug-render"`) to localize the bad stage with run-to-node > (`panel_run` `to_node_id`) by previewing intermediate steps. This guide is for > runs that fail with an error, OOM, or missing node. ## Error Diagnosis Strategy When a workflow fails, follow this approach: 1. Get the error. Use `get_history(action="diagnose")` to retrieve the execution result with the full traceback, plus any missing models/nodes 2. Check logs. Use `get_system_stats (action:"logs")` with keyword filters like `"error"`, `"warning"`, `"traceback"` 3. Identify the failing node. The history response includes the `node_id` and `node_type` that failed 4. Cross-reference inputs. Use `create_workflow (action:"node_info")` to verify the failing node's expected input schema 5. Check models. Use `list_local_models` to verify all referenced model files exist ## Out of Memory (OOM) ### Error Pattern ``` …

How to install
mdr add artokun/comfyui-mcp/troubleshooting@sha256:eea426b5af1b28c6The line at the top of this page pins the label git:20260825.ea35391, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
