It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Answers:

n8n versão = latest
database = postgres 16.3
running = docker
system = Amazon Linux 2023
Redis=redis 6 alpine
Executions process= own
