"panic: runtime error: invalid memory address or nil pointer dereference" when running "jfrog rt npmp"

[SomaSharath]

Describe the bug When running jfrog rt npmp --build-name={} --build-number={} , I get the following (similar to #1297 )

[Info] Running npm Publish

To Reproduce After I've upgraded the jFrog cli version to 2.6.1 the command fails with the above error, works fine with v2.5.1 version of cli.

Expected behavior Publishing npm package should not throw an error.

Screenshots If applicable, add screenshots to help explain your problem.

Versions

• JFrog CLI version: 2.6.1
• JFrog CLI operating system: Alpine Linux v3.11
• Artifactory Version: 7.24.4

Additional context As a temporary fix, I have rolled back the cli version to 2.5.1 and it works as expected.

Hi @SomaSharath , Thank you for reporting this issue. We just released version 2.6.2 that includes a fix. We'd appreciate your feedback for it.

Hi. The related issue https://github.com/jfrog/jfrog-cli/issues/1297 mentionned is not fixed by version 2.6.2

Seeing this issue in 2.71.5 looks like it's been open for 3 years, so I'm assuming theres no hope of a fix from jfrog

We were having the same issue and paniced ourselves just like the go panic.

We used "--detailed-summary" with the publish command( jf npm publish "--detailed-summary" ).
This stopped the panic: runtime error: invalid memory address or nil pointer.

Once the error was gone, identified issue with package.json/run that was caused by lack of git in the docker environment where we were building this. Fixing that root issue resolved the npm publish issue for us.

The memory panic error isnt useful, it should be handled in the jf cli code. As one of our lead developer says somewhere over here.. https://github.com/jfrog/jfrog-client-go/blob/40364ef34208461eba50c4d2eb878d726bb1df54/artifactory/services/utils/resultutils.go#L87
