Thanks for reporting this @DataScraper007. It looks like this is a Windows machine, and you're running the server manually rather than running the main HTTP Toolkit app, is that right?

[nirmal-actowiz]

Yes

I'm trying to understand how the server works because I'm not sure how or where it intercepts requests.

[pimterry]

Can you delete node_modules, and then run npm install and share all the output here? That should explain why this file is missing.

I'm trying to understand how the server works because I'm not sure how or where it intercepts requests.

It depends what you mean, but you're probably looking for either:

• The interceptors directory, which contains various interceptors that automatically configure certain targets (e.g. opening a browser, running a Docker container, or intercepting an Android device) to send traffic via HTTP Toolkit's proxy & trust HTTP Toolkit's CA certificate when you click an interception button in HTTP Toolkit. This is where all the client configuration happens.
• Mockttp, a separate library (although it is initialised and distributed as part of the server) which contains the actual proxy server and rules system. This is where all the actual networking is handled.

Hey ! Same error here
Here is what I did:

• Cloned repo
• npm install:

npm warn deprecated request-promise-native@1.0.9: request-promise-native has been deprecated because it extends the now deprecated request package, see https://github.com/request/request/issues/3142
npm warn deprecated rimraf@2.7.1: Rimraf versions prior to v4 are no longer supported
npm warn deprecated lodash.template@4.18.1: This package is deprecated. Use https://socket.dev/npm/package/eta instead.

This is coming from node-datachannel. Do you have postinstall scripts disabled? Like most native libraries, it uses a postinstall script to either download a prebuilt binary (if possible) or compile the native code locally (if not).

[iTrooz]

Looks like I had disabled them indeed ! No idea how that got there
Thank you, it works now
