Unshaped nodes errors in Time Series Analysis in SQL Server

[ismayc]

After re-running all of the SOLUTION code in https://campus-no-cache.datacamp.com/courses/20239/63394?ex=1, I've found the following exercises to have errors about unshaped nodes. I've also linked to the AST viewer for each exercise:

A recent antlr-tsql update addressed these.

@hermansje I'm still getting unshaped nodes errors when I try to run the examples above through either of the branches on campus at https://www.datacamp.com/teach/repositories/5004/branches/master. Can you confirm that these are working for you there?

[hermansje]

The AST viewer didn't have the update yet. @BogdanFloris will deploy it.

@BogdanFloris: Can you please deploy this? We had planned to launch the course this week and this is one of the last things left for the course.

It is now deployed!
