Hi,

Can you provide some information on your setup?

OS + version?
Is this an Electron or Node.js application?

[greettoroshan]

Hi Ben,

OS Windows 11 Enterprise

Version 22H2

This is a node.js application

and we are using these packages

"@itwin/core-backend": "^4.10.2",
"@itwin/core-bentley": "^4.10.2",
"@itwin/core-common": "^4.10.2",
"@itwin/core-geometry": "^4.10.2",

Thanks,
Roshan

Thanks.

Are you on a corporate proxy/VPN? Often this error indicates that there's a self-signed certificate in the request chain that Node.js cannot validate. We can prove this out by attempting to run the app outside of the network, if that's permissible.

If this is the case, a fix usually requires your IT dept. to whitelist the URL. To find them, you can enable trace-level logging, or use this node script to help debug.

Alternatively, if the self-signed certificate is on your local machine, you can tell node.js where to find it:

set NODE_EXTRA_CA_CERTS=/path/to/your/certificate.crt

# or:

npm config set cafile /path/to/your/certificate.crt

There is an npm package - win-ca - which attempts to load certs already in the Windows root certificate store. It's fairly straight-forward to install, so perhaps worth a try.

A very temporary work-around is to disable ssl validation before running your app:
export NODE_TLS_REJECT_UNAUTHORIZED=0

or

npm config set strict-ssl false
but this is not solution, just something to get you unblocked.

Let me know how it goes,
Ben
