Tasker automatically creates variables for the extras in an Intent Received trigger, but those variable names can (rarely) conflict with existing Tasker variables:

Giving an option to add a prefix to the extras' variable names, like in the Get Calendar Events action, would fix this issue without impacting the functionality of existing tasks, e.g. the conflicting %priority extra could be changed to %ntfy_priority.
