Hello @Deepika singh,

please refer to Error when creating subtask: "We couldn't create the subtask." | Jira | Atlassian Documentation

"Should you see this response, as an administrator, check the project settings:

1. On the sidebar, tap 'Project Settings' and check the 'Details' tab
2. There, ensure that 'Project Lead' and 'Default Assignee' fields have valid entries.

If the 'Default Assignee' is not a valid assignable user, the sub-task will not be able to be created. In this case, update the project settings to either 'Unassigned' or to a valid user and then 'Save'. This should address to error and allow you to create Subtasks as normal."

Cheers,

Lars
