While using this link. I am getting error as below-
{“errors”:
[{“message”:“Must specify exactly one of project, tag, or assignee + workspace”,“help”:“For more information on API status codes and how to handle them, read the docs on errors: Build an app with Asana”}]
}

Help me to resolve this error.

You need to use this endpoint to get the tasks that belong to a specific project GET /projects/:projectId/tasks.

You have to specify workspace OR project id, not both of them! and it will work!

You have to specify: “workspace + asignee” OR “project” NOT both!, and it will work!
