Thank you, as you pointed out it’s the job_data column that causes the error. Currently, Speedment doesn’t support the mapping of a bytea to a Blob.

There are a few possible options to work around this issue:

1. To create your own TypeMapper from bytea to Blob.
2. Express the value as a String and parse it manually.
3. Or lastly, change the column type to a Blob type.

OK thanks . I’ll update it.
