Unable to upload zip file through karate framework

I am trying to upload a zip file through karate framework using the stack overflow reference: put-requests-to-upload-a-file-in-form-data-using-karate and karate documents upload.feature

Please find the code below:

Given path 'upload'And header Content-Type = 'application/zip'And multipart file code = { read: 'file:tests/create/export.zip', filename:'export.zip', contentType: 'application/zip' }When method POSTThen status 200

We are getting the error as httpStatusCode="500"><links/><message>No ZIP data entries were found to import.</message>
