Thank you!

[NghiaTranUIT]

@Geczy I've fixed the ElectronJS issue, please get the Beta build from https://github.com/ProxymanApp/Proxyman/issues/1618#issuecomment-1528565327

[Geczy]

Can confirm it's fixed !

[ChiuMungZitAlexander]

My question is how can I disable it?

[NghiaTranUIT]

@ChiuMungZitAlexander Automatic Script doesn't start if you don't open the Terminal app. It only affects the current Terminal Session, not permanently change your OS. So, no need to disable it.

Hey @NghiaTranUIT :

version 3.6.1

I get this error when trying to open up a new 'automatic setup' terminal. I use

 fish -v
fish, version 3.6.1

[gkatsanos]

another issue I have (unrelated?) is even though I see one request, I dont see another one which happens to an external API endpoint but which passes through my VPN client.. could this be the reason?

[NghiaTranUIT]

@gkatsanos yes it can be a problem. If you're using fish, when opening the Automatic Setup Terminal -> Can you print the echo $PATH, to see if it contains the Proxyman path?

It's where Proxyman overrides the NodeJS env.

➜  ~ echo $PATH            
/Applications/Proxyman.app/Contents/Frameworks/ProxymanCore.framework/Versions/A/Resources/overrides/path

The reason is: there is a small warning from your log.

set: +a: invalid variable name. See `help identifiers`

add export NODE_TLS_REJECT_UNAUTHORIZED=0 after manual setup.

[NghiaTranUIT]

@leohxj a Beta build for you: https://download.proxyman.io/beta/Proxyman_4.11.0_Improve_UI_v1.dmg

Changelog

• Add export NODE_TLS_REJECT_UNAUTHORIZED=0

[leohxj]

thanks @NghiaTranUIT , it works well

[shirshak55]

actually I don't recommend this. Last week , I think from Egypt government was hacked because of http. Although, you may not be the target, I don't recommend messing with security.

I think proxy man should explicitly ask if they want to reduce this security?

[NghiaTranUIT]

@shirshak55 it doesn't globally modify your entire system. It only takes effect on the current Terminal app session when you need to debug your NodeJS project.

[leohxj]

yes, only for develop and use it locally

[tonyxiao]

Does this work with the built in node.js fetch now? Or is the node-fetch 3rd party lib required to use with proxyman?

[NghiaTranUIT]

It works for both. Native fetch and node-fetch

[tonyxiao]

Which env variable does native fetch use? When I look at the node docs it seems that fetch doesn't support proxy / agent agt all.

[NghiaTranUIT]

Auto Setup from Proxyman does more things than just the env. Proxyman uses global-agent to auto override the proxy of NodeJS Fetch in runtime.

You simply:

1. Open Proxyman, make sure you setup the certificate properly in Certificate menu -> Install for Mac.
2. Setup menu -> Auto -> start the Termnial.
3. Run your NodeJS script and this terminal and it's done ✅

[tonyxiao]

Hmm but the global-agent lib doesn't actually seem to support node 18 fetch. @see https://github.com/gajus/global-agent/issues/52 Does proxyman use the undici workaround too?

[NghiaTranUIT]

Yes, it's.

[NghiaTranUIT]

FYI: We can capture all HTTPS Traffic from NodeJS with the Auto Setup (https://docs.proxyman.io/debug-devices/nodejs)

No need to config the Proxy or manually trust the self-signed certificate on your NodeJS code 👍
