getSession() returning error

Whenever I request getSession() I am getting below always. Unable to understand what is happening. Will appreciate if someone can help.

Error fetching session: Error: app.66b0586b002b820a4e90@service.cloud.appwrite.io (role: applications) missing scope (account) at Client.call (/usr/local/server/src/function/node_modules/node-appwrite/lib/client.js:206:15) at processTicksAndRejections (node:internal/process/task_queues:96:5) at async Account.getSession (/usr/local/server/src/function/node_modules/node-appwrite/lib/services/account.js:947:16) at async checkSession (file:///usr/local/server/src/function/src/main.js:15:25) at async Module.default (file:///usr/local/server/src/function/src/main.js:85:22) at async execute (/usr/local/server/src/server.js:208:16) at async action (/usr/local/server/src/server.js:225:7) at async /usr/local/server/src/server.js:14:5
