Speedgrader not loading when submission type = external tool

[aniskadri]

Speedgrader shows an error:

"Couldn't find valid settings for this link"

I am sending the following params to the submission api

submission[type] = "basic_lti_launch"

submission[url] = "http://url_to_the_assignment"

More Info:

• the Placements in our lti are Assignment Selection
• Weirdly, Speedgrader loads everything correctly if I set the Placement to Editor Button, but that’s not an option for the particular user flow we have in mind.

What am I doing wrong? Should I be using the scores API instead when using external_tool in order to get speedgrader to work?

I also have this problem. It is kind of weird since Speedgrader was working correctly a few days ago
