Export EXECUTIONS_PROCESS=main Telegram Bot

Hello everyone, I have n8n installed via npm on Raspberry Pi4 (RAM 2GB), I ran the command through the terminal:

export EXECUTIONS_PROCESS=main

But the response in the Telegram bot is about 5 seconds for commands, what could it be?
When executing the command through the “export” terminal, I see:
declare -x EXECUTIONS_PROCESS="main"

How do you start n8n exactly?

N8n installed via npm, launched via pm2

Please check the following tutorial out. It explains how to run n8n with pm2 and how to set environment variables:

thanks))))

Your are welcome. Have fun!
