NoMethodError: undefined method `id' for nil:NilClass

Hello,

First of all I wanted to say that I love this lti_starter_app template, I'm working through some of the related YouTube tutorial videos on this template and they're proving very helpful; thank you so much for all of this content. Right now I appear to be at an impasse with an error in the code that won't allow me to proceed. I seem to be stuck at the database creation when I run rake db:setup and/or rake db:seed

When the script gets to the point of seeding the application instances, I run into this error:

CREATED ADMIN USER: [email protected] *** Seeding Sites *** Creating site: https://localhost:3000/ *** Seeding Applications *** Creating application: LTI Admin *** Seeding Application Instances *** rake aborted! NoMethodError: undefined method ``id' for nil:NilClass /Users/Dan/Documents_Local/devlocal/canvas/atomic_jolt/LTI_Starter/LTI-SAKs/lti_saks_4/db/seeds.rb:135:in ``block in setup_application_instances' /Users/Dan/Documents_Local/devlocal/canvas/atomic_jolt/LTI_Starter/LTI-SAKs/lti_saks_4/db/seeds.rb:133:in ``each' /Users/Dan/Documents_Local/devlocal/canvas/atomic_jolt/LTI_Starter/LTI-SAKs/lti_saks_4/db/seeds.rb:133:in ``setup_application_instances' /Users/Dan/Documents_Local/devlocal/canvas/atomic_jolt/LTI_Starter/LTI-SAKs/lti_saks_4/db/seeds.rb:196:in ``block in <top (required)>' /Users/Dan/Documents_Local/devlocal/canvas/atomic_jolt/LTI_Starter/LTI-SAKs/lti_saks_4/db/seeds.rb:187:in ``each' /Users/Dan/Documents_Local/devlocal/canvas/atomic_jolt/LTI_Starter/LTI-SAKs/lti_saks_4/db/seeds.rb:187:in ``<top (required)>' Tasks: TOP => db:setup => db:seed (See full trace by running task with --trace)

It seems to me that the main issue is traced to attrs = attrs.merge(site_id: site.id) on line number 135. I'm not sure that site_id is defined in the template initially, and any attempts to give it a numerical value in various ways (hard coding it in the seeds.rb, defining in the secrets.yml and in .env) have failed. Would someone be able to guide me to a solution for this error? Thank you so much!

It's possible that the site wasn't successfully created and so site.id was nil. Even in development we use a real URL - https://helloworld.atomicjolt.xyz. I wonder if using locahost:3000 fails validation.

Thanks for the response Justin. If my memory serves me, I had some trouble setting up a proper URL in my development space so I left it as localhost. Whenever I get some free time I'll give it another go and try to use a proper URL, then update the thread here on the status.
