Can someone help me? Production webhook does not execute workflow (HTTP 500, reading 'execute')

n8n Bug Report – Production Webhook Not Executing
##Describe the problem/error/question
When using the test webhook, the workflow executes correctly.

However, when switching to the production webhook, the workflow does not execute at all. No nodes run and no execution appears in the UI.

Testing the production webhook endpoint via ReqBin returns an HTTP 500 error. Recreating the workflow from scratch did not resolve the issue.
##What is the error message (if any)?
HTTP/1.1 500 Internal Server Error
{ “code”: 0, “message”: “Cannot read properties of undefined (reading ‘execute’)” }

I also did a test of creating workflows from scratch and testing the webhook, but when I added an HTTP request node, the workflow stopped working; it didn’t execute, it didn’t do anything, and no error message appeared.

No additional error is shown in the n8n UI.
Workflow
I can’t attach the file here because I’m a new user, so I’ll paste the workflow’s JSON code instead.
All credentials, API keys, private URLs and IDs have been removed.
Output of the last node
There is no output when the production webhook is triggered because the workflow does not start execution.

When using the test webhook, the workflow executes normally and returns the expected outputs.

Hi @Daniel_Matos

Please make sure you put the workflow json inside a code block else we are unable to use it.

Can you also please share your docker compose file or the command you used to start up your instance? Remember to REDACT any sensitive values like passwords and keys

Hi! I’m running n8n on Easypanel (Docker) with separate services: n8n_editor, n8n_webhook, n8n_worker, postgres and redis.

n8n version / image

n8n image: n8nio/n8n:2.2.4
execution mode: queue

n8n_editor (Environment) - REDACTED

DB_POSTGRESDB_DATABASE=$(PROJECT_NAME)
DB_POSTGRESDB_HOST=$(PROJECT_NAME)_n8n_postgres
DB_POSTGRESDB_PASSWORD=<REDACTED>
DB_POSTGRESDB_PORT=5432
DB_POSTGRESDB_USER=postgres
DB_TYPE=postgresdb

QUEUE_BULL_REDIS_HOST=$(PROJECT_NAME)_redis_n8n
QUEUE_BULL_REDIS_PASSWORD=<REDACTED>
QUEUE_BULL_REDIS_PORT=6379

EXECUTIONS_MODE=queue
EXECUTIONS_DATA_MAX_AGE=336
EXECUTIONS_DATA_PRUNE=true

GENERIC_TIMEZONE=America/Sao_Paulo
N8N_DIAGNOSTICS_ENABLED=false

N8N_EDITOR_BASE_URL=https://n8neditor.aureonvps.site
N8N_ENCRYPTION_KEY=<REDACTED>
N8N_HOST=n8neditor.aureonvps.site
N8N_PROTOCOL=https

NODE_ENV=production
NODE_FUNCTION_ALLOW_EXTERNAL=moment,lodash,moment-with-locales
N8N_LOG_LEVEL=debug
N8N_LOG_OUTPUT=file,console

Okay, if you need anything else, let me know!

Wouter_Nigrini · January 9, 2026, 11:29pm

I also need the docker compose or docker commands you used to start up your services.

Daniel_Matos · January 10, 2026, 12:07am

I’m running n8n on Easypanel (Docker). Easypanel manages the containers, so I don’t have a single docker-compose.yml file. Below are the docker start commands and the equivalent service details (secrets redacted).

Images

n8n_editor: n8nio/n8n:2.2.4
n8n_webhook: n8nio/n8n:2.2.4
n8n_worker: n8nio/n8n:2.2.4

Start commands (as configured in Easypanel)

# n8n_editor
n8n start

# n8n_webhook
n8n webhook

# n8n_worker
n8n worker --concurrency=5

Domain / Proxy (Easypanel)

n8n_editor: https://n8neditor.aureonvps.site → http://n8n_n8n_editor:5678
n8n_webhook domain is the same thing that n8n_editor on easypanel
n8n_worker doesn’t have domain on easypanel

Storage / Mounts (Easypanel)

volume “data” mounted to: /home/node/.n8n

Wouter_Nigrini · January 10, 2026, 12:17am

It’t very difficult to see what the actual configuration is you’re using. What I am trying to establish is whether your different containers are actually talking to each other.

Is there is a specific reason you’re using separate webhook processor containers?

Setting webhook processors is optional unless you’re planning to scale

Daniel_Matos · January 10, 2026, 12:52am

You’re right — env vars alone don’t prove connectivity. I ran internal DNS + TCP checks from the n8n_editor container console and confirmed the services can reach Postgres and Redis.

Hostnames from env

DB_HOST=n8n_n8n_postgres
DB_PORT=5432
REDIS_HOST=n8n_redis_n8n
REDIS_PORT=6379

DNS resolution (internal)

getent hosts n8n_n8n_postgres
# 10.11.0.8  n8n_n8n_postgres

getent hosts n8n_redis_n8n
# 10.11.0.9  n8n_redis_n8n

TCP connectivity (ports open)

nc -zvw3 n8n_n8n_postgres 5432
# ... open

nc -zvw3 n8n_redis_n8n 6379
# ... open

Why separate webhook/worker?

I’m using queue mode and set up separate services following the scaling pattern:

n8n_editor: n8n start
n8n_webhook: n8n webhook
n8n_worker: n8n worker --concurrency=5

Domain/Proxy currently points to editor:

https://n8neditor.aureonvps.site → http://n8n_n8n_editor:5678
(webhook/worker are internal only)
