/**
* An exception resulting from a structural error during JSON path evaluation.
*
* A structural error occurs when the JSON path expression attempts to access a
* non-existent element of a JSON array or a non-existent member of a JSON object.
*
* Note: in `lax` mode, the structural errors are suppressed, and the erroneous
* subexpression is evaluated to an empty sequence. In `strict` mode, the structural
* errors are propagated to the enclosing function (i.e. the function within which
* the path is evaluated, e.g. `JSON_EXISTS`), and there they are handled accordingly
* to the chosen `ON ERROR` option. Non-structural errors (e.g. numeric exceptions)
* are not suppressed in `lax` or `strict` mode.
