Parameterizing Request File Name in Karate's Read Method

When attempting to automate API testing using Karate, you might encounter an issue when trying to pass an XML file to the Read method, receiving an exception similar to the one mentioned in the question. This occurs when you use a variable to represent the file path within the Read method, like read(varXmlFile).

To resolve this issue, ensure that the variable is correctly defined beforehand. For example:

def varXmlFile = 'some-xml-file.xml'
Given request read(varXmlFile)

Alternatively, you can simply specify the file path directly within the Read method:

Given request read('some-xml-file.xml')

By following these methods, you can successfully parameterize the request file name in Karate's Read method and pass the desired XML file for your API testing automation.
