Hi,
I am using v. 4.7 of KNIME REST Client Extension, with the GET Request node.
Using Credentials to authenticate against GET Request with Digest as Authentication, give the error: Username may not be null
Test Case:
Url: https://httpbin.org/digest-auth/auth/user/passwd
Authentication: Digest
User: user
Password: passwd
Tested for: KNIME REST Client Extension, v. 4.7
