invalid add-on error while installing gmail addons

I am trying to install my gmail addons on another gmail account and getting "Invalid addons" error message.

I have selected "Enable developer add-ons for my account" checkbox and provided id.

It is already working on my main gmail account on which i have written appscript code.

Does anyone have this kind of issue?

Solution

we need to give read access to add-on's script project in order to install an add-on for @gmail.com.

It is already provided in the doc.
