要約
During migration of all the repositories to Git and Bitbucket, Bitbucket shows the following error, while navigating to one specific folder in one of the repositories:
"An error occurred while executing an external process: Unexpected end-of-stream reading tree for [<commit-hash-ID>]"環境
Bitbucket version: 7.6/7.7
Git version: 2.23.0/2.29.2
Operating system: Windows Server 2016
診断
- No issue when working with the repository with a Git client like clone or checkout.
- No issues when checking the repository with 'git fsck --strict'.
- This issue is only observed on the Bitbucket user interface and not on Git command line.

The cause of this issue could be because the repository having empty directory which was a PlasticSCM repository originally.
- PlasticSCM supports empty directories
- The repository was migrated to Git and pushed to Bitbucket Server
- Bitbucket Server encountered the empty directory in the repository and as it was unexpected threw the below error:
"An error occurred while executing an external process: Unexpected end-of-stream reading tree for [<commit-hash-ID>]"回避策
- Bitbucket Server does not have functionality to fix this
- This is not a bug within Bitbucket Server
- It is not likely that code will be added to Bitbucket Server to handle empty directories since Bitbucket Server was built to work with Git repository and Git, unlike PlasticSCM, does not index empty directories.
A possible workaround would be to:
- Add content to the directory, create a commit and push to Bitbucket Server. Bitbucket Server should allow you to navigate to the directory at that new commit since it will no longer have the empty
shathat will illicit this error - Rewrite history so the commit that added the empty directory is removed
If neither option is within the scope of your abilities the best strategy would be to retain the services of an Atlassian Partner and go over this issue with them so they can walk you through how to get all of the tree objects in the repo to a good state that will work with Bitbucket Server.
