NODE_FUNCTION_ALLOW_BUILTIN and Docker-Compose

Hey @Kirst, sorry for the late response. Ok the first example, the one with axios, will never get to the console.log as you are calling an async function without the await keyword. The function is returning before the HTTP request responds. With regard to the second example, it will not work either because the request library do not return a promise and the keyword await as far as I know works when the function you are calling return a promise. To make work you have to either require request-p…

If I am using the docker-compose file shouldn’t I be able to add a line to the environment section of n8n then restart and it should work with the proposed solution:

environment: 
- NODE_FUNCTION_ALLOW_BUILTIN=request-promise-native

I am still getting an error “Access denied to require ‘request-promise-native’”"

Thanks in advance.

Welcome to the community @ccarns!

The problem is that “request-promise-native” is not a built-in Node.js library. For that reason do you have to use instead of NODE_FUNCTION_ALLOW_BUILTIN the variable NODE_FUNCTION_ALLOW_EXTERNAL

Then everything should work fine.

Here the documentation:

Great to hear that I could help you and that you enjoy n8n!

Have fun!

@jan I was looking at this too and wondering if I can inject the NODE_FUNCTION_ALLOW_BUILTIN variables into n8n\dist\config\index.js if so how, or do I set it in the n8n.cmd file for my windows deployment. Thanks.

Ah no, users are never supposed to change anything within n8n. So in both locations nothing should be changed ever.

If you want to set that environment variable. In windows that should be:

SET NODE_FUNCTION_ALLOW_BUILTIN=crypto

And then you can start n8n normally.
