undefined method `tc_profile_url'

Hi,
I'm new with LTI and have been playing with this TP example but I'm getting the following error:

NoMethodError (undefined method `tc_profile_url' for #<IMS::LTI::Models::Messages::BasicLTILaunchRequest:0x007f85e82bbdd8>):

I have tried with lti_tool_consumer_example as consumer and the IMS LTI Tool Consumer emulator. I'm using the /register endpoint.

Looks like it is some method missing in the ims-lti gem.

Any ideas?

Thanks!

I'm getting the same error. Using the following repos and http://localhost:3000/register as the Provider launch url being submitted to the consumer tool. Any ideas on fixing the error?
