Answer 1

Write a Java utility to modify the file linkedInOauth2RESTInput.json before you do the upload. You can use the file: prefix instead of classpath:, so I recommend you save the temp file into the target folder, then you can do this:

Given multipart file properties = { read: 'file:target/linkedInOauth2RESTInput.json', filename: 'blob', contentType: 'application/json' }

But I agree that this is complicated, so I'm making a change to Karate so that you can instead of read, pass a value.

EDIT: this might also work depending on the server in this case:

* def tenantID = '2345';
* def json = read('classpath:ic/feature/REST/TestData/linkedInOauth2RESTInput.json')
* multipart field properties = json
