To prevent the duplication of tasks in Asana, you can use a combination of the "Watch Messages" trigger and filters in Make.
First, ensure that the search query in the "Watch Messages" trigger is correctly formatted to find emails with any of the user's categories applied. You can do this by using the "OR" operator to combine the search values, as suggested by community.make.com and community.make.com.
For example, if the user has 13 categories, the search query could be: category:(“Category 1” OR “Category 2” OR … OR “Category 13”)
Next, you can use filters in Make to check if the email has already been processed. You can use the "Get email" action to retrieve the email's ID and then use the "If" action to check if the email has already been processed. If it has, you can skip the rest of the scenario.

You can also use the "Get email" action to retrieve the email's ID and then use the "Update email" action to mark the email as processed. This way, you can keep track of which emails have already been processed and avoid duplicating tasks in Asana.
By using a combination of the "Watch Messages" trigger and filters in Make, you can prevent the duplication of tasks in Asana and ensure that only new emails are processed.
