git-client closeChannelException from RepositoryCallback

[Jin Wang]

Hello,

Could you please advice why i keep get closeChannelException from the RepositoryCallback when test on ECS agent.   

public static class Execution extends SynchronousStepExecution<String> {

  private static final long serialVersionUID = 1L;

  Execution(StepContext context) {

    super(context);

  }

  @Override

  protected String run() throws Exception {

    StepContext ctx = getContext();

    FilePath workspace = ctx.get(FilePath.class);

    TaskListener listener = ctx.get(TaskListener.class);

    EnvVars env = ctx.get(EnvVars.class);

    GitClient client = Git.with(listener, env).in(workspace).getClient();

    return client.withRepository(

        (RepositoryCallback<String>)

            (repo, channel) -> String.format("output from remote %s", repo.getFullBranch()));

  }

}
