Why is launch_presentation_document_target always "iframe"?

[jbaier]

According to the LTI standard and documented in the Edu App center, the LTI launch parameter launch_presentation_document_target should be window if the app has been launched in a new window or iframe if embedded. However, Canvas always sends the value iframe, even when "Load in a new tab" is checked.

My LTI Tool Provider works properly in Moodle. Am I doing something wrong, or is this incorrect behavior by Canvas?

I see the same thing, so I don't think you are doing anything wrong.

Looks like a Canvas issue.

I'm seeing this same issue, 'iframe' every time even when launched in a new window.

Does Canvas have any plans to update the launch_presentation_document_target to 'window' in the case that the LTI tool is launched in a new window?

My LTI Provider Tool needs to respond to iframed requests differently than new window requests, so having that parameter correctly populated would be very helpful.

Thank you!

Same. Go give this issue a "thumbs up"!
