Join StringExpression does not seem to work

Hail Query & hailctl

Hello,

I am using Hail 0.2.57-582b2e31b8bd and I want to create a new column in my table by joining strings from other columns but I cannot seem to make the join and if I try to run the example of the doc page (https://hail.is/docs/0.2/hail.expr.StringExpression.html#hail.expr.StringExpression.join) it does not work:

I am using a workaround by just adding + symbols in my strings to join them but I find this quite weird though.

I’m hoping someone can enlighten me.

The Hail str.join method was added in the last couple of versions, so if you update to 0.2.60, this should work.

Alright. Thank you for your reply.
