Issues with Node 25

[k-capehart]

Summary

I'm having issues with my custom SF CLI plugin when running tests for node version 25. I get the following error. It seems that Node.js 25 removes SlowBuffer, which breaks buffer-equal-constant-time, which is relied on for a few dependencies that I am having problems resolving. Any guidance on this would be appreciated.

TypeError: Failed to load plugin 'sf-plugin' declared in '.eslintrc.cjs': Cannot read properties of undefined (reading 'prototype')

@soridalac
Oh thank you for this. Considering I'm utilizing Salesforce's CI jobs for this, is there a way for me to set the NODE_DISABLE_VERSIONS environment variable from within my workflow? https://github.com/salesforcecli/github-workflows/blob/faf1269ce04ec5cde922dfcb0320391b58f3cb02/.github/workflows/unitTestsLinux.yml#L20C11-L20C65

@soridalac Would you look at that, I figured it out immediately after asking.

For anyone else, just add a repository variable in your repo's settings called NODE_DISABLE_VERSIONS with a value of 25.
