7. Troubleshooting¶

← Database Reference · Next: FAQ & Glossary →

Common problems and how to fix them. Issues are grouped by where they show up.

Installation & startup¶

`docker` or `node` "command not found"¶

The program isn't installed or isn't on your PATH. Re-run the prerequisite installs, then close and reopen your terminal so it picks up the new commands.

Docker says it can't connect / "daemon not running"¶

Docker Desktop isn't running. Launch it and wait for "Docker Desktop is running" before retrying.

The dashboard won't start / port 4400 in use¶

Another process is using port 4400. Stop it, or change DASHBOARD_PORT in your .env and restart the stack with docker compose up -d.

Google Sheets / Drive connection¶

Dashboard loads but shows no data / "permission denied"¶

Almost always one of:

The Sheet isn't shared with the service account. Open the Sheet → Share → add the client_email from your service-account JSON as Editor.
The private key is mangled. In .env, GOOGLE_SHEETS_PRIVATE_KEY must be on one line, wrapped in double quotes, with the \n sequences intact exactly as they appear in the JSON file. Don't reformat or add real line breaks.
Wrong GOOGLE_SHEETS_DATABASE_ID. Re-copy it from the Sheet's URL (the long part between /d/ and /edit).

"Save to Drive" fails with 403 Forbidden¶

The classic mismatch: the dashboard and the pipeline are using different service accounts. The pipeline created the Drive folder; the dashboard can't write into a folder it doesn't own access to. Fix: ensure GOOGLE_SHEETS_CLIENT_EMAIL in the dashboard matches the service account configured in n8n's Google credential, and that this account has Editor access to the ROOT_FOLDER_ID folder.

APIs not enabled¶

If Sheets/Drive/Docs calls fail outright, confirm all three APIs are Enabled in your Google Cloud project (Sheets, Drive, Docs).

n8n / pipeline¶

Clicking "Build" does nothing / trigger returns 503¶

The single most common setup failure is a webhook secret that doesn't match. The dashboard sends an X-Maestro-Secret header that must equal what n8n expects.

Confirm MAESTRO_WEBHOOK_SECRET in your .env is set (not blank).
Confirm the exact same value is in n8n's X-Maestro-Secret Header Auth credential, and that credential is selected on all three entry workflows' Webhook nodes.
A blank secret makes the dashboard's trigger routes return 503.
Also confirm N8N_WEBHOOK_BASE_URL ends in /webhook (not /webhook-test).

A workflow fails: "could not find workflow" / sub-workflow not called¶

The importer seeds and publishes the four entry workflows automatically; the agents, recorders, and sources are called as sub-workflows and do not need publishing. If trigger calls 404 right after first start, you likely skipped the one-time docker compose restart n8n that registers the entry webhooks. See Importing the Workflows.

After editing a sub-workflow's inputs, the parent passes wrong/empty data¶

Two likely causes:

Schema cache is stale. Click the refresh ⟳ icon on the parent's Execute Workflow node after changing the child's trigger schema.
A field is typed String instead of Object. Fields like config, critique, verifier must be Object in the trigger schema. String typing makes n8n stringify them, breaking lookups like config.model_X.

`#NAME?` errors in Google Sheets nodes¶

You mixed ={{ }} and {{ }} expression syntax, or manually typed a leading = in an expression-mode field. Use the syntax appropriate to that node type and don't hand-type the =.

JSON parse error in an agent, and output tokens equal the max¶

The model's response was truncated by the token cap. Raise that agent's max_tokens_* value in the config tab and re-run.

Agent throws "missing provider/model" instead of running¶

This is intentional, Maestro has no silent fallback model. The agent's provider_* / model_* key in config is blank or missing. Set it, and make sure the model has a matching row in the pricing tab.

A model_usage row shows `disabled` with all zeros¶

The agent's usage record wasn't forwarded (often a model name with no pricing row, or a disabled agent). Confirm the model exists in pricing and the agent is enabled in config.

`parent_execution_id` error from Data Loader¶

A caller invoked Data Loader without passing parent_execution_id = {{ $execution.id }}. This is a workflow wiring bug, add the input on the calling node.

A run crashed and left a job stuck as "running"¶

If the Run Error Handler isn't wired to that entry workflow, a crash can orphan run state. Set the workflow's Error Workflow (Settings → Error Workflow → Run Error Handler) so failures are captured and state is cleared. You can also reset stuck state manually in the run_state tab.

Discovery & scoring¶

Discovery returns nothing¶

Check watchlist_companies has companies with valid ATS slugs (greenhouse_slug, lever_slug, ashby_slug).
Check discovery_max_jobs_per_run isn't set so low that only one job survives ranking.
Bad slugs are logged in slug_failures, review and fix them.

Every job comes back "no fit" even good matches¶

This is the target/background collapse symptom. Confirm in config that target_* fields describe the role you want and that your profile_summary (which describes you) is not doubling as a target field. The two scoring axes must stay separated. See Architecture → two scoring axes.

Refine succeeds but the new version reads the wrong data¶

Test in order: build → polish → refine. The first refinement (a polish) reads version 1's original critique and verification. A later refine needs a prior polish to have written its verifier output. Running refine before any polish exists looks like a bug but isn't, there's no parent verifier row to read yet.

When all else fails¶

Trust live data over snapshots. The Database_Template.xlsx in the repo and any exports go stale quickly. The live Google Sheet is the source of truth.
Check the n8n execution log. Open the failed execution in n8n; the red node and its error message usually point straight at the cause.
Check run_errors. Catastrophic failures land here with an execution URL you can open directly.
Revert to the last working state rather than iterating on a broken workflow, re-import the workflow JSON from the repo if a node got mangled.
