Certificate issue after installing NPM package

[dimdusart]

Hello,

After executing npm i -g @cap-js/mcp-server in a local VSCode, the following error arises when trying to execute command cds-mcp :

node:internal/deps/undici/undici:12502
Error.captureStackTrace(err, this);
^

Hi @dimdusart ,

Thanks for reporting, I'm having trouble reproducing this. Could you kindly run

cds-mcp search_docs "bound action cds" 1

in a terminal outside VSCode?

Thanks and best regards,
David

Hello @David-Kunz,

I get the same issue. I run Powershell as admin, and cannot execute cds-mcp command directly (it says its not found for some reason), but executing npx cds-mcp give me the same issue :

Hi @dimdusart ,

Could you try to run the following Node.js script? #63 (comment)

It looks like something is blocking the fetch function execution.

Thanks and best regards,
David

Hi @dimdusart ,

It looks like your environment is blocking fetch calls. Could you review your system settings (proxies, ...)?
