Hi @rajesh_didshe

This is may be issue with the MAC M1 chip issue which does not support older frontend plugin.

Please refer the similar thread which solved the issue.

Hi @VeenaK,

Thanks for replay, but I'm not MAC user. Here It is showing unable to find valid certification path to requested target for downloading npm. for reference you can check above attach error note.

Hello @rajesh_didshe ,

For me I have noticed that for OKIX issue it has been certificate issue. Adding the cacert for the domain from which the download is attempted, to the java jre cacerts file has helped.

Please see if this is the case.

Sample steps for installing the cacerts - https://www.ibm.com/docs/en/tnpm/1.4.2?topic=security-import-certificate-jre-keystore

Thanks

Hi @Shubham_borole ,

Above WKND project is java 11 base and JRE no longer offered in JDK 11 Version, so not able to add cacerts.

Thanks,

[Shubham_borole]

Hi @rajesh_didshe , we are doing same for java 11 where the cacerts is located at "C:\Program Files\Java\jdk-11.0.11\lib\security" for example, basically the cacerts file is under '/libs/security' folder in case you are using mac you may need to find the equivalent.

Probably your issue is already resolved if its a mac. Just wanted to add the info. Thanks for responding.

Hi @Shubham_borole,

After hitting Keytool command getting FileNotFoundException for c:\temp\mdeCert.cer, any cue on this.

Thanks

[Shubham_borole]

@rajesh_didshe What command was run? and any snapshot?

[rajesh_didshe]

Hi @Shubham_borole,

Also tried cmd with admin elevated rights and attched screenshot for ref. Thanks for replay

Resolution:

Issue arises due to missing SSL certificate in the Java 11 keychain located in your Java11 jdk. Update the keychain with the certificate details will fix this issue.

1. Locate your JDK11 security folder: Mine is:  C:\Programs\java11\jdk-11.0.17\lib\security
2. Place the attached certificate in the location you prefer
3. Execute the following command from this jdk directory: keytool -import -trustcacerts -file C:\<<your location>>\_.nodejs.org.crt -keystore cacerts
1. Keystore password : changeit
2. Trust this certificate: yes
4. The certificate will be added to the key chain which will resolve the mentioned issue, try building the code again after the above steps.
