### Apache Iceberg version 1.7.1 (latest release) ### Query engine Flink ### Please describe the bug 🐞 I found a code suspected of being a bug while running rewrite data file flink action. Casting error occurs When binding the table structure and applying expression filter. From what I saw and understood the code, it seems to be an issue that occurred in the process of sanitize to string value. From the logic below, all value parameters delivered to the Object are delivered to the literal instance except for value method of the String Sanitizer. https://github.com/apache/iceberg/blob/apache-iceberg-1.7.1/api/src/main/java/org/apache/iceberg/expressions/ExpressionUtil.java#L514 Therefore, I think it would be right to modify it as follows. ``` java // ExpressionUtils.StringSanitizer private String value(BoundLiteralPredicate<?> pred) { return sanitize(pred.term().type(), pred.literal(), nowMicros, today); } // ExpressionUtils private static String sanitize(Type type, Literal value, long now, int today) { // same code } ``` or Change the pass parameters to literal.value() from where they are called. ### Willingness to contribute - [X] I can contribute a fix for this bug independently - [X] I would be willing to contribute a fix for this bug with guidance from the Iceberg community - [ ] I cannot contribute a fix for this bug at this time -- This is an automated message from the Apache Git Service.
