I am creating a canvas application in Salesforce Lightning, in which I am using just a link of my website to show that website in canvas to have my website looks like working in Salesforce Lightning.
For this, I have created a connected application and have choose Canvas Checkbox to make it Canvas application.
Then I have created a managed (beta) package in my developer org and have added connected App, lightning component bundle, lightning component page, and tab which will open my lightning page and will contain my canvas application. I am also adding screenshot of that:
After that, I have uploaded this package and got its link to install it on my other developer org. Then according to my requirements, it should create a new lightning component and page in new org and should show my website in canvas application inside that lightning component. It is showing Installed Package in my package list. You can see this in screenshot:
But it is not directly creating a visible tab in current application let say "Sales". And I am manually adding the tab in current selected application. And then I am opening that tab and getting the error:
So now if anyone can help me to get rid of this problem, I will be thankful to him.
