Getting error in file upload using karate api

Question

Could anyone please assist me to file upload functionality using Karate API? I have tried many ways, but getting error message as

"[{"title":"QUERY.BIZ.004","status":500,"detail":"Error in uploading document","timestamp":"2021-12-01T09:04:01.033+01:00"}]"

PAYLOAD DETAILS

metadata: {"key":"FILE_NAME","value":"karate-logo"}
metadata: {"key":"FILE_EXTENSION","value":"jpg"}
metadata: {"key":"TAG","value":"REQUEST"}
metadata: {"key":"DOC_TYP","value":"00008"}

Below mentioned karate API code which I used in the framework

Given url posturl
And path 'document'
And header id = '1608672'
And header Content-Type = 'multipart/form-data'
And multipart file file = { read: 'classpath:dataDrivenPayload/karate-logo.jpg', filename: 'karate-logo.jpg', contentType: 'image/jpg' }
And multipart field metadata = {"key":"FILE_NAME","value":"karate-logo"}, {"key":"FILE_EXTENSION","value":"jpg"}, {"key":"TAG","value":"REQUEST"}, {"key":"DOC_TYP","value":"00008"}
When method POST
Then status 200

Answer 1

I think the metadata needs to be sent as multiple "parts".

Try something like this:

* url 'https://httpbin.org/anything'
* multipart file metadata = { value: '{"key":"FILE_NAME","value":"karate-logo"}' }
* multipart file metadata = { value: '{"key":"FILE_EXTENSION","value":"jpg"}' }
* method post
* status 200
