A copyable error report template for debugging ComfyUI workflows
no3us · reddit · 2026-11-01
A Reddit user shares a copyable error report template for when a ComfyUI workflow fails, so others can reproduce the issue:
Required fields: install type (Desktop/portable/manual), ComfyUI version, GPU and VRAM, workflow JSON, model filenames, custom node named in the error plus its version, full error text, and the last change before it broke.
Practical tips:
- Attach a small replacement input that triggers the same failure; strip private inputs, tokens, and credentials first
- Keep a separate copy of the broken workflow and reduce it to a minimal reproducing graph if possible
- State where the failure occurs: model loading, sampling, decoding, or saving
- For wrong-looking results rather than crashes, attach the output and describe the expected difference; a graph screenshot aids orientation while the JSON lets others inspect connections
