Meteor.startup() script not working.

# Description
I'm doing the meteor-blaze tutorial todo application from scratch and encountered the issue in 2 places.
1. In step 02, when we first add dummy tasks using the startup script. On first run it gave me the error "count" deprecated use countAsync instead. When I fixed the issue and there are no more errors, I couldn't see the manually added tasks on the UI. I moved on to step 3 where we add a form in the UI to add tasks this is where I saw the db actually created tasks collection in the database which it failed to do using startup script in previous step.
2. In step 07 where we use startup script to create seed username and password. This time again it failed to create those user credentials. I'm attaching pictures with console error message for reference.

No source file or test is named. Reproduce tutorial steps 02 and 07 from the startup scripts, recording the Meteor version, operating system, and complete console errors; inspect the startup entry point involved in each step. Done means the script creates the sample tasks and seed user credentials and they appear in the application or database as expected.
