Hello @SD-ArunKumar 👋 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!

Closing the issue because it's missing the requested info about the CLI version/plugins. It doesn't say what you're deploying wen the error happens, what command you're running, etc.
