Hello. I have a problem with test case creating. After creating: ``` TestCase tc = testLinkAPI.createTestCase(summary, testSuite.getId(), ....); ``` Then `tc.getExternalId()` and `tc.getFullExternalId()` are null both. **Versions:** - TestLink: 1.9.20 - testlink-java-api: 1.9.20-1 - JVM 11 I need this external id to set keywords to test cases.
