When running the command that makes the login against our Sandbox org, it redirects to a localhost URL and then it display an error that doesn’t give us so much information
sfdx auth:web:login -a myuser@abc.com --instanceurl=https://xxxxx--xxxxx.my.salesforce.com
The error
Cannot read properties of undefined (reading ‘id’)
This is most likely not an error with the Salesforce CLI. Please ensure all information is accurate and try again.
This error can be related to the enhanced domain enabled or just the wrong URL typed in the login command. Read more about

Solution
To fix this error, add just “sandbox” to the URL so the pattern must be “xxxxxx–xxxx.sandbox.my.salesforce.com”
sfdx auth:web:login -a myuser@abc.com --instanceurl=https://xxxxxx--xxxx.sandbox.my.salesforce.com
