Patching 19c fails

[shahulnagoorkani]

While trying to apply 19 OJVM+DBRSU patch, we are getting the following error. We added some debug statements to print the variables and patch_dict variable is coming in as None. It seems like the task_vars[patch_dict] is set to None too. Any idea why are we getting this issue? Thanks for your help.

        print("Before try")
        try:

            print("Inside try")
            patch_id = int(db_item["patch_id"])
            print(patch_id)
            patch_dict = task_vars["patch_dict"]
            **print(task_vars["patch_dict"])**

            print("Before patch_item")
            patch_item = patch_dict[patch_id]
            print(patch_item)
            patch_item["patch_id"] = patch_id
            print(patch_item["patch_id"])
            args["patch_item"] = patch_item
            print("Last line in try block")
