Using Kobweb with NTLM proxy

[iainism]

Hi all,

Does anyone know the 'secret sauce' that will allow Kobweb to build and run when behind a corporate NTLM proxy please?

So far I have added my corporate proxy's signing certificate to cacerts (as our proxy performs a certificate insertion), added the proxy settings in the Idea settings ('Connection was successful'), and added proxy information within the project-level gradle.properties, e.g.

systemProp.http.proxyHost=proxy.path.net
systemProp.http.proxyPort=123
systemProp.https.proxyHost=proxy.path.net
systemProp.https.proxyPort=123

However when trying to build a new, empty project, I get the result:

Is there something else I should be doing please?

Ah-ha! I needed to tell NPM that it should use an extra certificate for chain of trust, as described here: https://stackoverflow.com/a/56239954/955198

I permanently added a (Windows) system variable, NODE_EXTRA_CA_CERTS, with the value set to a downloaded version of our proxy's root signing certificate in PEM format.

The build now runs to completion.

Note that setting the proxy properties (e.g. systemProp.http.proxyHost=proxy.path.net) in the gradle.properties is not required!

Sorry I couldn't share an answer here, I had no idea! Thank you for pushing through and sharing your update with us here.

My pleasure. Is it worth trying to summarise this somewhere in the documentation to save time for others that might hit the same issue?

[bitspittle]

I'm not sure. You're the first person I've heard bring it up. And now this discussion exists which I hope people can find?

Of course if any user comes to this discussion because they had the same issue, please let me know!
