I cannot get the uploaded file returned using codeignter3 fileupload() - file-upload

Question

I have the following code for file upload in the corresponding model file of codeigniter3.
$config['upload_path'] = './assets/img/report/';
$config['allowed_types'] = 'txt|odt|jpg|png|jpeg|pdf|docx';
$config['file_name'] = $this->id;
$config['overwrite'] = true;
$config['max_size'] = '150000';
$this->load->library('upload', $config);
if ($this->upload->do_upload('file')) {
return $this->upload->data('file_name');
}
return default.jpg;
The corresponding view file has the following code
<div class="form-group">
<label for="file">Attachment</label>
<input class="form-control-file"
type="file" name="file" />
<div class="invalid-feedback">
<?php echo form_error('file') ?>
</div>
</div>
But the code always returns default.jpg. How can I fix to return the uploaded file correctly. I use CI3 in Debian 11 running xampp8.1

**Configure your upload path**
After upload this will send you upload data or the upload error
$config = array(
'upload_path' => "./assets/img/report/",
'allowed_types' => "gif|jpg|png|jpeg|pdf",
'overwrite' => TRUE,
'max_size' => "2048000",
'max_height' => "768",
'max_width' => "1024"
);
$this->load->library('upload', $config);
if($this->upload->do_upload())
{
$data = array('upload_data' => $this->upload->data());
return $data;
}
else
{
$error = array('error' => $this->upload->display_errors());
}
}
