npm install issue

[brindha-mec]

Hi,

I am trying to install content toolkit and I have posted this message in that community as well. Posting here as it is failing when installing the @OracleJet dependency -

Getting these exceptions when running npm install -

127 verbose stack FetchError: request to https://registry.npmjs.org/@oracle%2Foraclejet failed, reason: unable to get local issuer certificate
127 verbose stack at ClientRequest. (C:\Program Files\nodejs\node_modules\npm\node_modules\minipass-fetch\lib\index.js:130:14)

As mentioned in the logs, this is the node version : v18.17.0 and npm version: v9.6.7
Also, downloaded the certificate from this URL : https://registry.npmjs.org/@oracle%2Foraclejet and added to the cafile property and also tried adding the NODE_EXTRA_CA_CERTS value in the System environmental variables. Most of the forums suggesting to make the strict-ssl as false; I cannot do this as per our company policy. Also, should I be using any other node/npm versions? Anyone has come across this kind of error before? please advise.
