N8N Ignores HTTP/HTTPS Proxy Environment Variables When Connecting to External Services (e.g., Notion)

[Lerr1uqs]

Bug Description

I have set the http_proxyand https_proxyenvironment variables in my command line. However, when n8n tries to access Notion, it does not use the proxy (I see no activity in my proxy software).
I started n8n with the debug log level enabled using the following command in PowerShell:

$env:N8N_LOG_LEVEL='debug'; n8n

The debug logs do not show the message "Installing global HTTP proxy agents," which suggests the proxy settings are not being recognized. The connection to Notion ultimately fails.
It appears that n8n is not respecting the standard HTTP proxy environment variables for its outbound connections to external services like Notion.

To Reproduce

$env:HTTP_PROXY="http://127.0.0.1:7890"
$env:HTTPS_PROXY=$HTTP_PROXY
n8n

You can see that the traffic does not go through the proxy client.

Expected behavior

access external server through local proxy.

No, it hasn't been resolved yet. I'd greatly appreciate your help with this issue.

[Lerr1uqs]

seems like need to add axiosConfig.proxy = process.env.http_proxy in AxiosRequestConfig

export async function invokeAxios(
	axiosConfig: AxiosRequestConfig,
	authOptions: IRequestOptions['auth'] = {},
) {
	try {
		return await axios(axiosConfig);
	} ·····
}

there have no .proxy assignment.

this patch work, seems like .proxy not be assigned properly. (not case sensitive problem, I tried both capital and small)

@Lerr1uqs
i have tried to resolve that i think the issue with to accessible for both uppercase and lowercase..can you check my pull request is that working?

[Akcthecoder200]

i will try another approach to resolve it?

$env:HTTP_PROXY="http://127.0.0.1:7890";$env:HTTPS_PROXY=$HTTP_PROXY; n8n not work too. Maybe this isn't case sensitive problem. I think it due to devoloper forget to set proxy in axios http request config.
The AI tell me axios not use node http proxy(installGlobalProxyAgent) in default.
