Hello @tothszabolcs :wave: It looks like you didn't include the full Salesforce CLI version information in your issue. Please provide the output of version --verbose --json for the CLI you're using (sf or sfdx).

A few more things to check:

• Make sure you've provided detailed steps to reproduce your issue.
  • A repository that clearly demonstrates the bug is ideal.
• Make sure you've installed the latest version of Salesforce CLI. (docs)
  • Better yet, try the rc or nightly versions. (docs)
• Try running the doctor command to diagnose common issues.
• Search GitHub for existing related issues.

Thank you!

hi @tothszabolcs / @JGN5496 - I followed the same commands used in your CI, and it worked for me

Hi @WillieRuemmele. Unfortunately, I still have the error and have no idea why. There are more detailed steps in the linked issue. Did you also try those? If yes, and you still cannot reproduce the issue, then do you have any pointers as to where I should look? Thank you in advance for your help!

hi @tothszabolcs - I've confirmed it's an issue with node 25

 ➜  node -v                 
v25.0.0
➜  dreamhouse-agents git:(main) ✗  hub:(GLOBAL - DevHub)
 ➜  sf plugins install sfdx-git-delta
    TypeError: Cannot read properties of undefined (reading 'prototype')
➜  dreamhouse-agents git:(main) ✗  hub:(GLOBAL - DevHub)
 ➜  nvm use 24

Hi @WillieRuemmele

Sorry for the late response, there was a long weekend, so I couldn't check the solution until now. Thank you for the response and the help, I reverted the node install to version 24 and it is working again.

Are there any plans to making this work with node 25?

[WillieRuemmele]

yes, we'll be working on adopting 25

[sjurgis]

If someone stuck with this - I use NVM so I had to delete v25 of node from ~/.nvm/versions/node - otherwise somehow it was defaulting to v25 after each new shell launch.
