get_node_types_in_workflows opened workflow files with json.load(open(path, "r")), which uses the platform's default encoding. On Windows that is cp1252, so any workflow containing non-ASCII text raised UnicodeDecodeError, was swallowed by the per-file except, and vanished from the result entirely. Open with encoding="utf-8-sig" instead (workflows are always UTF-8, and may carry a BOM), and use a with-block so the handle is no longer leaked. The scan also only walked the root "nodes" array. Subgraph definitions live in a flat definitions.subgraphs list and their nodes never appear there, so every node inside a subgraph was invisible - and the instance node's type is the subgraph's UUID, so a meaningless uuid was reported in place of the real node types. Extract the per-node work into collect_node_types_in_graph, which indexes the subgraph definitions by id and, on reaching a node whose type names one, descends into that definition rather than reporting the uuid. It also picks up definitions nested on a subgraph and carries a visited set so a self-referencing subgraph cannot recurse forever. The response shape is unchanged, so getWorkflowNodeTypes needs no changes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
/manager/queue/start and /manager/queue/reset are registered POST-only, but
uninstallNodes and the node usage analyzer called them through fetchApi with no
options, which sends a GET. The request failed, so the task worker never ran:
each uninstall was queued successfully and then sat there untouched. Because
the response was ignored, the UI still reported success and asked the user to
restart ComfyUI - after which the queue was gone and nothing had been removed.
Every other caller in the codebase already passes { method: 'POST' }; add it to
the five call sites that did not, and check the start response in
uninstallNodes so a failure here is reported instead of presented as success.
The uninstall endpoint also keys off json_data['id']. custom-nodes-manager.js
backfills that field from the pack key, but the analyzer passed the pack
through untouched, and packs absent from the node DB carry no 'id' - those were
queued with a null node name and died in unified_uninstall on node_id.lower(),
visible only as a traceback in the terminal. Backfill 'id' the same way, and
set 'hash' so ui_id is no longer undefined.

Addresses two review findings. collect_node_types_in_graph tested membership on node values directly, so a null node, or a node with a null "properties" value, raised TypeError. The caller catches that and never appends the mapping, meaning one malformed entry made the entire workflow disappear from the report. Guard that each node is a dict and read "properties" via get(). A non-list "nodes" value had the same effect and is now skipped with a warning - the endpoint's `"nodes" not in workflow_file_data` check does not catch `"nodes": null`. queue_start returns 201 when a worker is already running, in which case it goes on to consume the items just queued. uninstallNodes accepted only 200, so it would report a failure and skip onSuccess even though the uninstall was proceeding. The status precheck in uninstallNodes uses the same predicate as the 201 branch, but the confirm dialog sits between that check and the start call, so a worker started meanwhile lands here. Accept both 200 and 201. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

A list or dict node type reaches `node_type in subgraph_definitions` and raises TypeError because it is unhashable; the per-file handler catches it and drops the whole workflow from the report. Null and numeric types did not raise but were emitted into the result as junk entries. The isinstance(node, dict) guard added previously covered the node object but not the values inside it. Check the type is a string before the subgraph lookup, which closes all four cases. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

A non-string cnr_id was copied straight into the response. On the client, analyzeWorkflowUsage hands it to findPackageByCnrId, which falls through the direct key lookup and calls cnrId.toLowerCase() - not a function on a list, dict, number or bool. Neither analyzeWorkflowUsage nor the analyzer's loadData catches it, so the whole usage analysis dies and the panel stays on "Analyzing node usage ...". Only copy cnr_id when it is a string. ver is left as-is: no client code reads it, so there is nothing to break. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

1 participant
Three bugs in the workflow node-usage feature, found while trying to work out why the analyzer under-reported packages and why Uninstall Selected did nothing. All were verified against a real install (52 installed packs, 29 workflows).
1. Workflows are read with the platform's default encoding
get_node_types_in_workflowsusedjson.load(open(path, "r")). With noencoding, Python uses the platform default — cp1252 on Windows. Any workflow containing non-ASCII text raisesUnicodeDecodeError, which the per-fileexceptswallows, so the workflow disappears from the response with only a warning.2 of my 29 workflows failed this way, example of errors:
Now opened with
encoding="utf-8-sig", which handles a BOM if present and plain UTF-8 otherwise. Also wrapped in awithblock — the old form leaked the file handle.2. Nodes inside subgraphs are never scanned
The loop only walked the root
nodesarray. Subgraph definitions live in a flatdefinitions.subgraphslist and their nodes never appear there, so everything inside a subgraph was invisible. Worse, a subgraph instance node'stypeis the subgraph's UUID, so a meaningless5eb5cfa6-f140-40b7-…was reported in place of the real node types.Added
collect_node_types_in_graph, which indexes the definitions by id and, on reaching a node whose type names one, descends into that definition instead of emitting the uuid. It also registersdefinitionsnested on a subgraph, and carries a visited set so a self-referencing subgraph can't recurse forever.Packages that only became visible after this change, on two of my workflows:
video_wan2_2_14B_i2v.jsonUnetLoaderGGUF(comfyui-gguf),ImageResizeKJv2,TorchCompileModelAdvanced(kjnodes)image_krea2_turbo_t2i.jsonwent from 5 reported entries to 28.The JSON response shape is unchanged, so
getWorkflowNodeTypes()needs no changes.3. "Uninstall Selected" silently does nothing
/manager/queue/startand/manager/queue/resetare registered POST-only, butuninstallNodesincommon.jsand four call sites innode-usage-analyzer.jscalled them viafetchApiwith no options — which sends a GET. Confirmed against a running instance:So each
POST /manager/queue/uninstallqueued its task fine, thestartcall failed, and the worker never ran. The JS ignored that response and went straight toonSuccess(), telling the user to restart ComfyUI — after which the queue is gone and nothing was ever removed.Every other UI in the repo (
custom-nodes-manager.js,model-manager.js,comfyui-manager.js) already passes{ method: 'POST' }. Added it to the five call sites that didn't, anduninstallNodesnow checks the start response instead of reporting success unconditionally.Related: the uninstall endpoint keys off
json_data.get('id').custom-nodes-manager.jsbackfills that from the pack key, but the analyzer assignedoriginalData: packraw — and packs absent from the node DB carry noid, sonode_namewasNoneandunified_uninstallraised onnode_id.lower(), caught by the worker's bareexceptand visible only as a terminal traceback. 7 of my 52 installed packs were in that state, and they'd still have failed after fixing the 404, soidis now backfilled the same way (plushash, which was feedingui_idasundefined).Testing
collect_node_types_in_graphover all 29 workflows in a real user directory: all parse (3 previously failed outright), no UUIDs leak into the output, subgraph contents are picked up.manager_server.pycompiles.Not addressed
installModelsinnode-usage-analyzer.jsposts custom-node installs to/manager/queue/install_model(the model endpoint, not/manager/queue/install). It's unreachable — nothing in that UI renders an install button — so I left it alone, but it's wrong if anyone wires it up.
