ERROR running force:source:beta:pull: Cannot read properties of null (reading 'length')
Summary
I'm using the beta version to pull the changes in my instance org but I'm getting the following error: Cannot read properties of null (reading 'length'). Even though the error is raised, the process continues and downloads the latest changes from the instance as expected.
I'm not working with a scratch org but a sandbox instance for development. Thanks!
Steps To Reproduce:
- Check for changes:
sfdx force:source:beta:status -r -u [org] - Pulls the latest changes:
sfdx force:source:beta:pull -f -u [org]
Expected result
Local sources should be updated with the changes pulled from the remote sandbox org.
Actual result
The local sources are updated but the process throws the following error first:
$ sfdx force:source:beta:pull -f -u [org]
ERROR running force:source:beta:pull: Cannot read properties of null (reading 'length')

Sometimes I get a more details:
$ sfdx force:source:beta:pull -f -u AuctionAngelaDev

Are you able to share what metadata type caused this to happen, and what the change was (create, modify, delete) that leads to the error?
And around how many changes were in that transaction?
Any way to reliably recreate the error?
Sure, for example, I was just working on changing a custom apex class (removing an old method that won't be used anymore) and updating the API version in the class from 44 to 53.
This is the output for: sfdx force:source:beta:status -r -u [org]

Hi, that's quite an old version you're running, can you please try upgrading the CLI to the latest version (possible the latest-rc) and try the command again, source tracking library has undergone several changes since then.
I am getting a simliar error in Powershell on Windows 10 using CLI 7.167.2 (sfdx-cli/7.167.2 win32-x64 node-v16.17.0)

We fixed a bug in a library that was causing some commands to throw this error some months ago, I'll close this issue but if someone still experience this on latest please do open a new issue.
