System.ArgumentException when reading an array field with a composite type consisting of an enum based domain #2278
Steps to reproduce
I've created a self-contained project to reproduce the issue:
Reading a column of an array of a composite type with domain members fails with an exception. One of the member types of the composite is a domain type with a base type of enum. It's only when reading where the issue is and writes to the column works as expected.
