I can’t see why …

node-wa# n8n-node-dev build

Build credentials and nodes
=========================
The nodes got build and saved into the following folder:
/root/.n8n/custom
node-wa# grep require *ts
const os = require('os');
const axios = require('axios');
node-wa# n8n-node-dev build

@minstrel Axios it’s not a builtin library you need to use NODE_FUNCTION_ALLOW_EXTERNAL instead.

Thanks ricardo, but no effect …

#!/bin/sh
#
export NODE_FUNCTION_ALLOW_BUILTIN=*
export NODE_FUNCTION_ALLOW_EXTERNAL=axios
n8n

Resolved by using built-in request

Ah yes, I think there was a misunderstanding. NODE_FUNCTION_ALLOW_BUILTIN and NODE_FUNCTION_ALLOW_EXTERNAL only show effect in the Function-Node within n8n but you are creating a totally new node so that does not have any effect.

Yesss, my mystake jan, the documentation tells it!
