Solutions

1. The expression has an unexpected type. Supply an expression of the expected type.

When it happens

Trigger: A runtime precondition of the Hibernate query API is violated: Expected '<value>' expression but got '<value>'

Common situations: Application code or configuration calls the query API in a way that violates its documented contract; the interpolated values in the message identify the offending input.
