Review Comment:
Nit: I found it was a bit confusing to read the error message instance:
`Correlated column references do not support data type map<string,int>: v1.x`.
Basically `v1.x` as an expression was not clear in the error message.
For example to me this is more clear: `Correlated column references do not
support expression v1.x due to unsupported data type map<string,int>`.
Something like this.
