LTI Content-Item Message 404

Hello,

 

I'm using the AWS pre-configured blackboard image "Blackboard Learn for REST and LTI Developers".

 

I'm attempting to test the LTI's deep linking standard or "Content Item Selection".

 

I've set up an LTI Tool Provider and created a "Content-Item Message" placement type.

I then log in with my test faculty account and access my test course. In the left menu I select content then in Build Content I select my LTI Tool. This generates an LTI request to the tool provider.

KeyValue
accept_media_typesapplication/vnd.ims.lti.v1.ltilink,image/*,text/html
content_item_return_urlhttps://ourtest.blackboard.com/webapps/blackboard/controller/lti/contentitem
lti_message_typeContentItemSelectionRequest
rolesurn:lti:role:ims/lis/Instructor

 

 

The user selects an assignment and the TP ,using the value of content_item_return_url, posts:

 

Header 1Header 2
data_3_1::_10_1::::false::false::_2_1 
lti_message_typeContentItemSelection
lti_versionLTI-1p0
content_itemsJSON

 

I receive a 404 status code and this error: The specified resource was not found, or you do not have permission to access it.

 

Any idea why posting to the return url would give a 404?
