Constant READ_BMOPF_FIELD_NOT_A_NUMBER 

pub const READ_BMOPF_FIELD_NOT_A_NUMBER: &str = "READ.BMOPF.FIELD_NOT_A_NUMBER";

A BMOPF field the schema types as a number holds something else. Severity Error: the field reads as NaN, which serializes on as an unbounded limit, so the parse states a fact the source never gave.
