I’ve noticed an issue with the Asana trigger, there is an option to enter a resource, which can be a project or a task. I’ve entered a project id, however, the trigger still triggers events event with projects that do not match the project id.
Asana has acknowledged this bug and is reportedly working on a fix. However, no specific timeline for resolution has been provided. (as you can see this post on the issue on Asana forum is from 2021 : )
