Git Clone error Azure Function site extension

[rikroe]

Hi,
when trying to install Batch Shipyard to an Azure Function, I'm getting a weird Access Denied error in git clone....
This is the output of Kudu:

ExitCode: 1, Output: D:\Program Files\Git\cmd\git.exe
D:\Program Files\Git\bin\git.exe

It's possible that a branch was getting force pushed at the same time you were cloning. Can you try re-running the install? You may need to perform it manually (see the docs).

I can't do a manual install from D:\home\SiteExtensions\BatchShipyard as nothing gets cloned - I've tried a couple of times during the day. It's weird as apparently git (started by kudu/nuget) is unable to find the respective branch at the remote (presumably github).

Would a fully manual install (manual git clone from master and then following the Azure Functions instructions work)?
Edit: In the Windows installation instructions the need for having Python 3.6 in PATH is stated. Is that possible/needed for Azure Functions? If so, how can I achieve that?

[alfpark]

Sorry, I missed this:

"Batch Shipyard tag ??3"

That's an invalid tag. It might have something to do with the fact that the version.txt file in the Nuget package is encoded as UCS-2 LE BOM and perhaps a change happened with the site extension installer environment.

I'll see if I can force ASCII/UTF-8 encoding for the version.txt file generated with the extension package in a future version.

In the meantime, you can delete the version.txt file in D:\home\SiteExtensions\BatchShipyard and create a new file version.txt with the text 3.6.1 (with no newline). Then try re-running the install.cmd file.

Not totally sure what fixed it for me. I tried creating the version.txt in D:\home\SiteExtensions\BatchShipyard, D:\home\SiteExtensions\batch-shipyard and also in D:\home\batch-shipyard (because that is where the nuget package apparently tries to clone) but did not work.

Then I restarted the site via Kudu and afterwards in D:\home\SiteExtensions\BatchShipyard the install.cmd and (wrongly encoded) version.txt are there. So changed the version to 3.6.1 and the install is currently running. Many thanks!
