I am trying to import a azure devops repo to a new repo within the same project. The following code just returns “Bad Request” and no other information.

public async Task ImportGenericRepository(GitRepository destinationRepository, GitRepository genericRepository, Guid serviceEndpointId)
{
    var importRequest = new GitImportRequest
    {
        Repository = destinationRepository,
        Parameters = new GitImportRequestParameters
        {
            GitSource = new GitImportGitSource
            {
                Url = genericRepository.RemoteUrl,
                Overwrite = false
            },
            DeleteServiceEndpointAfterImportIsDone = true,
            TfvcSource = null,
            ServiceEndpointId = serviceEndpointId
        },
    };
           
    try
    {
        await _connection.GitHttpClient.CreateImportRequestAsync(importRequest, _projectId, destinationRepository.Id);
    }
    catch (Exception ex)
    {
        throw;
    }

}

I tried doing this directly with the HttpClient, I got the same error.
