This is the same error as in #2247

This result in %GitVersion_NuGetVersionV2% not having any value.

Get hold of %GitVersion_NuGetVersionV2%

Actual Behavior

%GitVersion_NuGetVersionV2% has no value

Possible Fix

Steps to Reproduce

GITVERSION_REMOTE_USERNAME=access_token
GITVERSION_REMOTE_PASSWORD=empty

Install giversion.portable. Version 5.6.11 was installled
choco install gitversion.portable

Run
gitversion /l console /output buildserver /updateAssemblyInfo

I tried to install 5.3.0 but it gave the same error.

Are you sure you're not setting GITVERSION_REMOTE_PASSWORD to anything and that GITVERSION_REMOTE_USERNAME holds the value of the access token? Just look at the changes in #2248 to see how the logic works.

[be-prokom]

Yes. The access token I am using has been working until now, but this token has been added by someone else. Can the problem be that the token is not valid any more? In case, how can I create a new one?

[asbjornu]

Sorry, but I don't know anything about your infrastructure or where this access token even comes from.

[be-prokom]

Ok, but do you know if this error can appear if the access token is invalid?

[asbjornu]

As the exception is thrown by LibGit2Sharp, I have no idea, sorry.
