Can't get rootAccount.id, account_uuid from LTI handshake

[10618071]

I have the following xml as part of my LTI request. Please notice the 3 underlined lines below. These 3 lines are not returning any data. Does anyone see a problem?

According to <!-- - Canvas LMS REST API Documentation , this data should always be available.

<lticm:options name="custom_fields">
<lticm:property name="custom_canvas_lms">$lms</lticm:property>
<lticm:property name="custom_canvas_api_domain">\$Canvas.api.domain</lticm:property>

<lticm:property name="custom_canvas_user_id">\$Canvas.user.id</lticm:property>

Jared are you getting data for the other variables too? I've never seen the preceding "\" before the "$". I did some testing with custom fields settings in the UI and the "\" made the parameter fail to populate with the expected value, but I haven't had a chance to test via XML config yet.

I thought I'd follow up here and say it there is no actual problem. Just user error . The issue was that I didn't reinstall the LTI after I updated my code. As a result, Canvas had old xml. Everything worked fine when I updated it.
