Hi @bayya.vuragayala,

Thank you for sharing your issue. The error message says:
“Cannot invoke ‘com.kms.katalon.entity.testcase.TestCaseEntity.isAPITestGenerationTestCase()’ because ‘tc’ is null.” This typically occurs in Katalon Studio when an operation tries to use a test case object (tc), but that object is not properly initialized or does not exist.

Possible Causes:

  1. The test case is missing or deleted:

    • The tc variable might refer to a test case that no longer exists in your project.

  2. Corrupted test case data:

    • The metadata for the test case could be damaged.

  3. Improperly configured API test case:

    • The associated settings or test object might be incomplete.

  4. Script editor issues:

    • The script may have syntax or logic errors where the tc object is accessed.

Steps to Fix:

  1. Verify the Test Case:

    • Ensure the test case exists in your project and is accessible. Check its location in the Test Explorer.

  2. Check API Test Case Settings:

    • Double-check the configuration of the test case (e.g., request objects, endpoints, or variables).

  3. Look for Initialization Issues:

    • If you’re using a script, make sure the tc variable is initialized properly before it’s accessed.

  4. Repair the Project:

    • Use File > Reload from Disk in Katalon Studio to refresh your project in case of file corruption.

  5. Debug in Script Mode:

    • Open the script editor for the affected test case and ensure there are no unresolved variables or calls.

Thank you!
