Could you please share the course/lab name?

I am doing Claude Code For Beginners first lab for doing /init

[Santosh_KodeKloud]

Thanks. It really helps if you share the lab name with your query.

If you are pointing out this error, then yes. Claude has recently released opus-4.8, and it appears the new installation defaults to it, which is not configured for the labs.

I’ll ask the team to fix this.

The lab is fixed now.
Thanks for your patience and support
