The Wiert Corner – irregular stream of stuff

When using git 2.19.1 on Windows, you will likely get a NullReferenceException during pull/push/fetch operations on https connections.

Easiest workaround is to downgrade to 2.19.0: [WayBack] git pull fatal: NullReferenceException encountered. On an local instance of Bitbucket · Issue #1868 · git-for-windows/git · GitHub

I am seeing the same thing using 2.19.1 against our internal Bitbucket server. Reverting back to 2.19.0 the problem no longer occurs.

Harder workaround is to install the Git Credential Manager 1.18.1: [WayBack] git pull fatal: NullReferenceException encountered. On an local instance of Bitbucket · Issue #1868 · git-for-windows/git · GitHub.

[WayBack] Release Git Credential Manager for Windows v1.18.1 · Microsoft/Git-Credential-Manager-for-Windows · GitHub

Bug Fixes:

• Fixes Null Reference exceptions when parameters or contentType are not populated

To install the Git Credential Manager, download and double-click the GCMW-1.18.1.exe installer. It is that easy, it will even install Git for Windows 2.17.0 and the Microsoft .Net Framework for you if necessary.

Hopefully that one will integrated in a minor update to git for Windows soon: [WayBack] git pull fatal: NullReferenceException encountered. On an local instance of Bitbucket · Issue #1868 · git-for-windows/git · GitHub

moderately soon, hopefully, there will be a minor version release of Git for Windows that will include the updated GCM v1.18.1. [just need more volunteer time for the PR and tests ;-)
That should eliminate the `Fatal: NullReferenceException” but appears not to fix the #1874https://github.com/git-for-windows/git/issues/1874 delays. (still to hear from the OP if the issue is definitely the AV, or something elese)

If you really dare, you can try the nightly snapshot which already includes GCMW-1.18.1: [WayBack] git pull fatal: NullReferenceException encountered. On an local instance of Bitbucket · Issue #1868 · git-for-windows/git · GitHub

the next official Git for Windows version will have a new Git Credential Manager version. Also, the current snapshot at https://wingit.blob.core.windows.net/files/index.html should have it already.
