3. Which release version of this package are you using?
v2.6.1
4. What did you do? If possible, provide a recipe for reproducing the error.
Just updated to v2.6.1 and after that, up my docker normally and see the message:

5. What did you expect to see?
Before that, I was using swooletw v2.5.0 and everything worked normally
Just to be sure, I did a rollback for v2.5.0 and works fine.
