Power BI PostgreSQL Dataflow Geom column error

I am connecting to a PostgreSQL database and want to import several tables with a geom data column.

However, when I connect to the table (PostgrSQL connector in either Power BI Desktop or Power BI Service Dataflow) the geom column shows as

The error reads as...

An error happened while reading data from the provider: 'We don't support CLR type 'Microsoft.Mashup.Engine1.Runtime.ValueException'.'

How can I view the geom data?  All the other columns load without an issue.  Each entry in the column is 59,330 characters long

Hey @Anonymous ,

 

Create view on PostgreSQL and convert the geom datatype to WKT (Well Known Text), this thread provides samples how this can be done: https://stackoverflow.com/questions/49905207/convert-postgres-geometry-format-to-wkt

 

Hoepfully,  this provides what you are looking for.
