Cannot access to the lab.

[gboron]

I am doing an Engineer Data for Predictive Modeling with BigQuery ML course. I completed first three labs (60% completed) and I have a problem with fourth lab: Cloud Composer: Copying BigQuery Tables Across Different Locations. I cannot open it (it does not have a hyperlink in a course view). When I use a direct link to the lab I am moved to the Dashboard page with a message: Sorry, access denied to this resource. What should I do?

This laboratory has been cancelled. You can upgrade the course and you will no longer be able to see this laboratory.
