taskwarrior calling task import from a hook does not add tags

To report a bug...

i was testing my hook and for some reason it was modifying a task but not adding the desired tag after reading the haskell-taskwarrior library source code and my own and not finding any errors i went to debug with taskwarrior to get a better idea of the problem

What command(s) did you run? task add test +next and then task id done
What did you expect to happen? my hook would run and then it would modify the correct task's tag via task import
What actually happened? my hook ran and it called task import with the correct arguments but the task wasn't modified, i was using debug =1 and debug.hooks = 2 and from the output my hook works as expected i even tried echo json-ouput | task import and when i did this it updated the task's tag correctly which means that it must be an error when calling task import specifically from a hook here is the command's output

just wondering why you are using task import in an on-modify hook, usually it takes old and new task on stdin (old being empty if new task) and writes task to insert on stdout. resulting task will get modified or added by taskwarrior itself without hook calling import.

i want to modify a task that isn't the one being completed.The idea is to bump the urgency of a task of the project with lowest number of task completions in the past 2 weeks, so i may want to modify any task and not only the one being completed.

The use case makes sense. Maybe the database gets locked by the process that forks on-modify hook? Just a guess. Also have you tried using a temporary file instead of stdin? and giving that as file argument to task import?
