Adalennis opened a new issue, #9285:
URL: https://github.com/apache/hop/issues/9285
### Apache Hop version?
2.20.0
### Java version?
Java 21
### Operating system
macOS
### What happened?
Found while testing the Text chunker on 2.20.0 (code unchanged on main).
**1. Metadata fields that already exist in the input get the wrong type**
When the input already has String fields called `chunk_index` or
`total_chunks`, the chunker does not add its own fields: it writes Long values
into the existing String fields. With Sort rows on `chunk_index` after the
chunker, the pipeline finishes, but saving the execution information fails:
chunk_index String : There was a data type error: the data type of
java.lang.Long object [4] does not correspond to value meta [String]
Expected: a check error or renamed output fields.
**2. An overlap that is not a number becomes 0**
Chunk overlap `abc`: the check reports "Chunk overlap cannot be negative",
which isn't the problem, and at runtime the transform runs with overlap 0
(chunk 2 starts at 100 with size 100). An invalid chunk size (`abc`) stops the
transform with "Chunk size must be greater than 0". Both should give the same
kind of error, with a message that says the value is not a number.
