| How do I fix WorkerDeclarationError? |
|
Textual version 0.31.0 requires that you set thread=True on the @work decorator if you want to run a threaded worker.
If you want a threaded worker, you would declare it in the following way:
@work(thread=True)
def run_in_background():
...
If you don't want a threaded worker, you should make your work function async:
@work()
async def run_in_background():
...
This change was made because it was too easy to accidentally create a threaded worker, which may produce unexpected results.
