issue using check compare-with --dir .

[Andrea-Fan]

I'm working with towncrier on a git repo. Towncrier on local works fine and when using it with check command it finds the fragment correctly.
I've also added a job to a gitlab pipeline that checks the fragments when opening a merge request. The job looks like this
sh 'pip install poetry '
sh 'pip install towncrier==23.6.0'
sh 'poetry run towncrier check --dir .'
when running that job towncrier fails with this output

Hi,

Can you link your CI config file?

Do you pull the full repo history and branch references when you checkout / close the repo inside the CI ?

Most of the time a CI will do a quick shallow clone.

I downloaded the code using GIT in a docker, executed MYPY, and then ran the code 'towncrier check --dir .'. Isn't it a file-checking method ., why does it give GIT related errors

pipeline {

agent {
    label 'linux-docker'
}

stages {
    stage('Run Tests'){
       agent {
            docker {
                label 'linux-docker'
                image 'thekevjames/nox:2023.4.22'
                args '-u root:root'
                reuseNode true
            }
        }
        stages{
            stage('Mypy') {
                steps {
                    sh 'nox -s mypy'
                }
            }
            stage('Check Changelog') {
                steps {                          
                    script { 
                        sh 'pip install   poetry  '
                        sh 'pip install towncrier==23.6.0'
                        sh 'poetry run towncrier check --dir  .'

I am not sure what are you trying to do here :)

Can you add more info?

towncrier check needs full access to the git repo history.

In this way it can check if the current branch has a newsfragment added in comparison with the main branch.
