Error related to appid displayed and icon is broken

[sureshkumar2004]

Downloaded the repo and ran the command : npm start , added the extension from dist folder , opened Gmail and got the following error on top . Although i have generated the app id , there are no instructions on how to add it to the code. So looked at the older instructions and modified the code in content.js line : InboxSDK.load(2, "Hello World!").then((sdk) => { , inserted the appid in place of "Hello World!" string , that did not work.

, the icon shows up in compose but is broken.

How to fix both these issues.
